[0017] The following are suitable implementation methods, while referring to the appendix. Figure 1 The processing machine of the present invention will be described in detail below.

[0018] [One Implementation Method]

[0019] The processing machine of one embodiment will be described using the accompanying drawings. Figure 1 This is a perspective view showing the machining machine of this embodiment. Here, the case where the machining machine 10 is a wire electrical discharge machining (EDM) machine will be described as an example, but the machining machine 10 is not limited to a wire EDM machine.

[0020] The machining machine 10, namely the wire electrical discharge machining machine, is used to process the workpiece W (reference) in a machining fluid. Figure 1 A machine tool that performs electrical discharge machining on workpiece W by applying voltage to the workpiece W and the wire electrode 12, thereby generating a discharge between the workpiece W and the wire electrode 12. The machine tool 10 is equipped with a machine body 14, a machining fluid treatment device 16, and a control device 18.

[0021] The material of the wire electrode 12 is, for example, a tungsten-based, copper-alloy-based, or brass-based metal. On the other hand, the material of the workpiece W is, for example, an iron-based or superhard metal.

[0022] The main body 14 of the processing machine is equipped with a supply system 20a and a recovery system 20b. The supply system 20a supplies the wire electrode (electrode) 12 to the object being processed (workpiece, workpiece) W, and the recovery system 20b recovers the wire electrode 12 after it passes through the object being processed W.

[0023] The supply system 20a is provided with a bobbin 22, a torque motor 24, and a brake shoe 26. The bobbin 22 winds the unused wire electrode 12. The torque motor 24 imparts a torque to the bobbin 22. The brake shoe 26 imparts a frictional braking force to the wire electrode 12. The supply system 20a is also provided with a brake motor 28 and a wire guide (upper wire guide) 32. The brake motor 28 imparts a braking torque to the brake shoe 26. The wire guide 32 guides the wire electrode 12 above the work W. The torque motor 24 and the brake motor 28 are provided with encoders EC1, EC2 that detect a rotational position or a rotational speed. The control device 18 can perform feedback control of the torque motor 24 and the brake motor 28 in such a manner that the rotational speeds of the torque motor 24 and the brake motor 28 reach prescribed rotational speeds, based on detection signals detected by the encoders EC1, EC2. In addition, the supply system 20a can further be provided with a tension detection portion 30 that detects the magnitude of the tension of the wire electrode 12.

[0024] The recovery system 20b is provided with a wire guide (lower wire guide) 34, a pinch roller 36, and a feed roller 38. The wire guide 34 guides the wire electrode 12 below the work W. The pinch roller 36 and the feed roller 38 can hold the wire electrode 12. The recovery system 20b is also provided with a torque motor 40 that imparts a torque to the feed roller 38. The recovery system 20b is also provided with a recovery tank 42. The recovery tank 42 recovers the used wire electrode 12 that is transported by the pinch roller 36 and the feed roller 38. The torque motor 40 is provided with an encoder EC3 that detects a rotational position or a rotational speed. The control device 18 can perform feedback control of the torque motor 40 in such a manner that the rotational speed of the torque motor 40 reaches a prescribed rotational speed, based on a detection signal detected by the encoder EC3.

[0025] The machine main body 14 is provided with a machining tank 46. The machining tank 46 can store a machining liquid such as deionized water or oil used at the time of electric discharge machining. The machining tank 46 is placed on a base portion 48. The wire guides 32, 34 are arranged inside the machining tank 46. The work W is disposed between the wire guide 32 and the wire guide 34. The wire guides 32, 34 are provided with eye mold guides 32a, 34a that respectively support the wire electrode 12. In addition, the wire guide 34 is also provided with a guide roller 34b. The guide roller 34b guides the wire electrode 12 toward the pinch roller 36 and the feed roller 38 while changing the orientation of the wire electrode 12.

[0026] In addition, the wire guide 32 sprays clean machining liquid that does not contain machining chips (sludge) toward the interelectrode gap formed by the wire electrode 12 and the work W. Thereby, the interelectrode gap can be filled with clean machining liquid that is suitable for electric discharge machining. As a result, it is possible to prevent a decrease in the precision of electric discharge machining due to sludge generated by electric discharge machining. In addition, the wire guide 34 can also spray clean machining liquid that does not contain sludge toward the interelectrode gap.

[0027] The workpiece W is supported by a machining table (not shown) that can move along the X and Y directions. The line guides 32 and 34, the workpiece W, and the machining table are immersed in the machining fluid stored in the machining tank 46.

[0028] When a start hole or machining groove is formed on the workpiece W to serve as the starting point for electrical discharge machining, the wire electrode 12 is inserted into the start hole or machining groove to connect the wire electrode 12. In this case, the gap between the start hole or machining groove of the workpiece W and the wire electrode 12 becomes the electrode gap. After the machining machine 10 connects the wire electrode 12 by inserting it into the start hole or machining groove of the workpiece W, it moves the machining table (workpiece W) in a plane parallel to the XY plane while feeding the wire electrode 12 downwards (in the -Z direction) toward the workpiece W. Thus, the workpiece W can be machined. The connection of the wire electrode 12 means that the wire electrode 12 wound on the winding spool 22 is passed through the wire guide 32, the workpiece W, and the wire guide 34 and held by the clamping roller 36 and the feed roller 38. When the wire electrode 12 is connected, the wire electrode 12 is given a specified tension. Furthermore, the X and Y directions are orthogonal to each other, and the direction orthogonal to the XY plane (horizontal plane) is defined as the Z direction. Additionally, the workpiece W may not necessarily have a start hole or machining groove formed on it to serve as the starting point for electrical discharge machining. For example, sometimes machining may begin (cut into) from the end face of the workpiece W. In such cases, machining can begin from the end face of the workpiece W without needing to insert the through-wire electrode 12 into the start hole or machining groove.

[0029] The processing fluid treatment device 16 is a device that manages the water quality of the processing fluid by removing processing debris generated in the processing tank 46 and adjusting parameters such as resistance (resistivity) and temperature. The processing fluid, after being treated by the processing fluid treatment device 16, is returned to the processing tank 46. At least a portion of the processing fluid returned to the processing tank 46 is ejected from the wire guide 32 and returns to the processing tank 46. The control device 18 can control the processing machine body 14 and the processing fluid treatment device 16.

[0030] Figure 2 This is a block diagram showing a portion of the processing machine according to this embodiment.

[0031] like Figure 2 As shown, the main body 14 of the processing machine (reference) Figure 1 The machining center is equipped with a motor 50. The motor 50 is used to move the wire electrode 12 relative to the workpiece W. For example, a servo motor can be used as the motor 50, but it is not limited to this. Multiple motors 50 are provided in the machining center body 14, but for the sake of simplicity, [the following is omitted as it is not directly related to the motor description]. Figure 2 The diagram shows one motor, 50.

[0032] The power supply section 52 repeatedly applies a voltage pulse to the work W and the wire electrode 12 in accordance with a control signal supplied from the control device 18. In addition, like the use Figure 1 As described above, the machining main body 14 is equipped with the constituent elements other than these constituent elements, but Figure 2 Only a part of the constituent elements is shown in the figure.

[0033] The machining main body 10 is also equipped with a voltage sensor 54A. The voltage sensor 54A can detect the voltage between the electrodes (inter-electrode voltage). The information indicating the inter-electrode voltage detected by the voltage sensor 54A can be supplied to the control device 18.

[0034] The machining main body 10 is also equipped with a current sensor 54B. The current sensor 54B can detect the current flowing to the inter-electrode. The information indicating the current detected by the current sensor 54B can be supplied to the control device 18.

[0035] The machining main body 10 is also equipped with an encoder 54C. The encoder 54C is equipped on the motor 50. The encoder 54C can be an absolute encoder or an incremental encoder. The information detected by the encoder 54C can be supplied to the control device 18.

[0036] The machining main body 10 is also equipped with a temperature sensor 54D. The temperature sensor 54D can detect the temperature of the machining liquid. The information indicating the temperature detected by the temperature sensor 54D can be supplied to the control device 18.

[0037] The machining main body 10 is also equipped with a pressure sensor 54E. The pressure sensor 54E can detect the hydraulic pressure of the machining liquid. The information indicating the pressure detected by the pressure sensor 54E can be supplied to the control device 18.

[0038] The machining main body 10 is also equipped with a specific resistance sensor 54F. The specific resistance sensor 54F can detect the specific resistance of the machining liquid. The information indicating the specific resistance detected by the specific resistance sensor 54F can be supplied to the control device 18.

[0039] In this way, the machining main body 10 is equipped with a plurality of sensors 54A to 54F. The symbol 54 is used when the sensors are generically described, and the symbols 54A to 54F are used when each of the sensors is described.

[0040] The control unit 18 manages the control of the entire processing machine 10. The control unit 18 is equipped with an arithmetic unit 56, a storage unit 58, and a communication unit 86. The arithmetic unit 56 may be composed of a processor such as a CPU (Central Processing Unit), but is not limited thereto. The storage unit 58 is equipped with, for example, volatile memory (not shown) and non-volatile memory (not shown). Examples of volatile memory include RAM (Random Access Memory). Examples of non-volatile memory include ROM (Read Only Memory) and flash memory. Programs, data, etc., can be stored in the storage unit 58. The communication unit 86 is used for communication with the information management unit 88, external devices 90, etc., which will be described later.

[0041] The arithmetic unit 56 is equipped with a machining control unit 59, an acquisition unit 60, a comparison unit 62, a determination unit 64, and a display control unit 66. By executing the program stored in the storage unit 58, the machining control unit 59, the acquisition unit 60, the comparison unit 62, the determination unit 64, and the display control unit 66 can be implemented.

[0042] The storage unit 58 is equipped with an information storage unit 80, a form 82, and an operating procedure manual storage unit 84.

[0043] The information storage unit 80 can store arrangement information 79A to 79G, which will be described later (see reference). Figure 3 When referring to arrangement information in a general sense, symbol 79 is used; when describing individual arrangement information, symbols 79A to 79G are used. Furthermore, the information storage unit 80 can store processing information 85A to 85H, which will be described later (see reference). Figure 3 The symbol 85 is used to refer generally to information during processing, and the symbols 85A to 85H are used to describe information during each processing step. Furthermore, the information storage unit 80 can store processing result information 87A to 87C, which will be described later (see reference). Figure 3 The symbol 87 is used when referring to processing result information in a general sense, and the symbols 87A to 87C are used when describing individual processing result information.

[0044] As will be described later, Table 82 is based on baseline information 97A (reference). Figure 6 ) and Comparison Information 97B (Reference) Figure 6 The differences between them determine the parts that need to be maintained or checked.

[0045] The work procedure manuals used for inspection and processing are stored electronically in the work procedure manual storage section 84.

[0046] The processing machine 10 is also equipped with a display section (display) 68. The display section 68 can be constituted by a liquid crystal display or the like, for example, but is not limited thereto. The display section 68 is equipped with a display screen 72. The display of the display section 68 can be controlled by the display control section 66.

[0047] The processing machine 10 is also equipped with an operation section 70. The operation section 70 can be constituted by a touch panel, keyboard, mouse, or the like, which are not shown, for example. The touch panel can be equipped on the display screen 72 of the display section 68. The operator can give an instruction to the control device 18 by operating the operation section 70. The operator can select a selection button, icon, or the like by operating the touch panel, mouse, or the like, for example.

[0048] The processing control section 59 controls the motor 50, power supply section 52, or the like as appropriate in accordance with the processing conditions, processing program, and various information fed back by the sensor 54, which are set in advance, thereby performing electric discharge processing on the processing object W.

[0049] When performing inspection processing, the operator performs input of information related to the schedule of the inspection processing, that is, schedule information 79. The input of the schedule information 79 is performed by the operator in a state in which an operation screen for inputting the schedule information 79 is displayed on the display section 68. Figure 3 A diagram showing an example of the display screen. As shown in Figure 3 The input frame (text box) 77 for inputting the schedule information 79 can be displayed on the display screen 72 of the display section 68. The operator can input the schedule information 79 in the input frame 77 by operating the operation section 70. Further, an example in which the input frame 77 is displayed is shown here, but a drop-down list can also be displayed. Further, the processing-in-progress information 85 and the processing result information 87 have not yet been acquired at the stage in which the input of the schedule information 79 is performed. Therefore, the processing-in-progress information 85 and the processing result information 87 are blank at the stage in which the input of the schedule information 79 is performed.

[0050] As shown in Figure 3As the arrangement information 79, for example, information 79A, 79B related to the wire electrode 12 used in the inspection machining can be cited. Further, as the arrangement information 79, for example, information 79C, 79D related to the work W can be cited. Further, as the arrangement information 79, for example, information 79E indicating the machining program used in the inspection machining can be cited. Further, as the arrangement information 79, for example, information 79F indicating the machining conditions at the time of the inspection machining can be cited. Further, as the arrangement information 79, for example, information 79G indicating the person in charge at the time of the inspection machining can be cited. As the wire electrode 12 related information 79A, information 79A related to the material of the wire electrode 12 can be cited. As the wire electrode 12 related information 79B, information 79B related to the diameter of the wire electrode 12 can be cited. Further, as the work W related information 79C, information 79C related to the material of the work W can be cited. As the work W related information 79D, information 79D related to the thickness of the work W can be cited. Further, the arrangement information 79 is not limited to these. Further, as described above, the job manual storing section 84 stores electronically the job manual used at the time of the inspection machining. The operator can perform the input of the arrangement information 79 while referring to such a job manual as appropriate. The acquisition section 60 can acquire the arrangement information 79 thus input. After the input of the arrangement information 79 is completed, the operator clicks the save button 89. When the save button 89 is clicked, the acquisition section 60 stores the acquired arrangement information 79 to the information storing section 80.

[0051] The on-site adjustment is performed at the time when the machining tool 10 is set in a factory or the like. The setting of the machining tool 10 in a factory or the like is usually performed by the personnel on the manufacturer side of the machining tool 10. Thus, the operator in the inspection work performed at the time of the on-site work is the personnel on the manufacturer side. On the other hand, at the time of the periodic inspection, the setting is usually performed by the user of the machining tool 10, and the personnel on the manufacturer side of the machining tool 10 does not appear.

[0052] The arrangement is performed at the time of the inspection machining performed at the time of the on-site adjustment or the like, and at the time of the inspection machining performed at the time of the periodic inspection or the like, respectively. In the case where the contents of the arrangement at the time of the periodic inspection or the like are different from the contents of the arrangement at the time of the on-site adjustment or the like, the machining state at the time of the inspection machining is likely to differ, and it is even likely to affect the machined product obtained by the inspection machining. Thus, to evaluate the result of the periodic inspection or the like accurately, it is preferable that the contents of the arrangement of the inspection machining performed at the time of the on-site adjustment or the like are the same as the contents of the arrangement of the inspection machining performed at the time of the periodic inspection or the like. However, the contents of the arrangement of the inspection machining performed at the time of the on-site adjustment or the like can differ from the contents of the arrangement of the inspection machining performed at the time of the periodic inspection or the like.

[0053] After the inspection and processing arrangements are completed, the inspection and processing are carried out. During the inspection and processing, the acquisition unit 60 acquires processing information 85. The processing information 85 is information indicating the processing status of the workpiece W during inspection and processing. The processing information 85 can be automatically acquired by the acquisition unit 60 based on information supplied from various sensors 54. Figure 3 As shown, processing information 85 may include, for example, processing voltage-related information 85A. Furthermore, processing current-related information 85B may be listed as processing information 85. Furthermore, processing speed-related information 85C may be listed as processing information 85. Furthermore, processing temperature-related information 85D may be listed as processing information 85. Furthermore, processing hydraulic pressure-related information 85E may be listed as processing information 85. Furthermore, resistivity-related information 85F may be listed as processing information 85. Furthermore, processing time-related information 85G may be listed as processing information 85. Furthermore, processing date and time-related information 85H may be listed as processing information 85, etc.

[0054] The processing voltage is the voltage applied between the workpiece W and the wire electrode 12. The processing voltage can be acquired by the acquisition unit 60 based on information supplied from the voltage sensor 54A. For example, the acquisition unit 60 can acquire the average voltage per unit time when processing a specified part of the workpiece W as the processing voltage.

[0055] The processing current is the current flowing between the workpiece W and the wire electrode 12 when a discharge occurs. The processing current can be acquired by the acquisition unit 60 based on information supplied from the current sensor 54B. For example, the acquisition unit 60 can acquire the average current per unit time when processing a specified part of the workpiece W as the processing current.

[0056] The processing speed is the processing speed at which the workpiece W is inspected. The processing speed can be obtained by the acquisition unit 60 based on information supplied from the encoder 54C. For example, the acquisition unit 60 can obtain the processing speed at which a specified part of the workpiece W is processed.

[0057] The processing temperature is the temperature of the processing fluid. The processing temperature can be acquired by the acquisition unit 60 based on information supplied from the temperature sensor 54D. For example, the acquisition unit 60 can acquire the average processing temperature from the start to the end of the inspection processing of the workpiece W as the processing temperature, but it is not limited to this.

[0058] The machining hydraulic pressure is the hydraulic pressure of the machining liquid. The machining hydraulic pressure can be acquired by the acquisition section 60 from information supplied from the pressure sensor 54E. For example, the machining hydraulic pressure can be acquired by the acquisition section 60 as the average value of the machining hydraulic pressure from the start to the end of the inspection machining of the machining object W, but is not limited thereto.

[0059] The specific resistance is the specific resistance of the machining liquid. The specific resistance can be acquired by the acquisition section 60 from information supplied from the specific resistance sensor 54F. For example, the specific resistance can be acquired by the acquisition section 60 as the average value of the specific resistance of the machining liquid from the start to the end of the inspection machining of the machining object W, but is not limited thereto.

[0060] The machining time is the time required for the inspection machining of the machining object W. The machining date and time is the date and time when the inspection machining of the machining object W is performed. In addition, the machining information 85 is not limited to these pieces of information. After the inspection machining is performed, the operator clicks the save button 89. When the save button 89 is clicked, the acquisition section 60 stores the acquired machining information 85 to the information storage section 80.

[0061] After the inspection machining is performed, the input of the machining result information 87, which is information obtained by measuring the machined product obtained by the inspection machining, is performed by the operator. The machining result information 87 is obtained by measuring the machined product obtained by the inspection machining using a measuring device. The input of the machining result information 87 is performed by the operator in a state where an operation screen for inputting the machining result information 87 is displayed on the display section 68. As shown in Figure 3 the input frame (text box) 95 for inputting the machining result information 87 can be displayed on the display screen 72 of the display section 68. The operator can input the machining result information 87 in the input frame 95 by operating the operation section 70.

[0062] As shown in Figure 3As the processing result information 87, dimensional information 87A can be cited, as shown. In addition, as the processing result information 87, straightness-related information 87B can be cited. Further, as the processing result information 87, surface roughness-related information 87C or the like can be cited. Note that the processing result information 87 is not limited to these. The straightness is the magnitude of the deviation of a linear body from a geometrically correct straight line. The dimensions of the processed object can be measured, for example, using a micrometer, a non-contact three-dimensional measuring instrument, a contact three-dimensional measuring instrument (CMM: Coordinate Measuring Machine), a microscope, or the like. The straightness of the processed object can be measured, for example, using a micrometer, a non-contact three-dimensional measuring instrument, a contact three-dimensional measuring instrument, or the like. The surface roughness of the processed object can be measured, for example, using a surface roughness measuring instrument or the like. Note that the case where the processing result information 87 is input by the operator is exemplified here, but is not limited thereto. The processing result information 87 that is automatically supplied from the measuring instrument can be acquired by the acquisition unit 60. In addition, the case where a plurality of pieces of processing result information 87 are acquired by the acquisition unit 60 is exemplified here, but is not limited thereto. For example, the processing result information 87 acquired by the acquisition unit 60 can be only one piece. The acquisition unit 60 can acquire the processing result information 87 thus input. After the input of the processing result information 87 is completed, the operator clicks the save button 89. When the save button 89 is clicked, the acquisition unit 60 stores the acquired processing result information 87 in the information storage unit 80.

[0063] Figure 4 A diagram showing an example of the configuration of the information storage unit is shown in FIG. 8. As shown in FIG. 8, the information storage unit 80 is equipped with a plurality of storage areas 81A to 81H. Figure 4 As shown in FIG. 8, the information storage unit 80 is equipped with a plurality of storage areas 81A to 81H. Figure 4 An example in which eight storage areas 81A to 81H are equipped is shown in FIG. 8. The symbol 81 is used when the storage areas are described in general, and the symbols 81A to 81H are used when the respective storage areas are described. The storage area names of the respective storage areas 81A to 81H are, for example, memory#0 to memory#7.

[0064] The arrangement information 79, the processing-in-progress information 85, and the processing result information 87 acquired by the acquisition unit 60 at the time of the on-site adjustment can be stored as the reference information 97A (refer to FIG. 9) in any one of the plurality of storage areas 81. Figure 6

[0065] Note that the case where the information acquired at the time of the inspection processing performed during the on-site adjustment is exemplified here as the reference information 97A, but is not limited thereto. A plurality of pieces of processing-in-progress information 85 and processing result information 87 in the inspection processing performed after the on-site adjustment can be the reference information 97A.

[0066] ​After on-site adjustments are made, periodic inspections can be conducted whenever the scheduled inspection time arrives. During periodic inspections, the arrangement information 79, processing information 85, and processing result information 87 obtained by the acquisition department 60 can be used as comparison information (comparison object information) 97B (reference). Figure 6 ) Store to any of the multiple storage regions 81.

[0067] The comparison unit 62 can compare the reference information 97A with the comparison information 97B. As described above, the reference information 97A includes multiple arrangement information 79, multiple processing information 85, and processing result information 87. Furthermore, like the reference information 97A, the comparison information 97B also includes multiple arrangement information 79, multiple processing information 85, and processing result information 87. That is, the reference information 97A contains multiple items. In addition, the comparison information 97B contains multiple items corresponding to the multiple items included in the reference information 97A. The comparison unit 62 can compare the content of each item in the reference information 97A with the content of each item in the comparison information 97B on a per-item basis.

[0068] Figure 5 This diagram illustrates an example of a display screen on a display unit. For example... Figure 5 As shown, the display control unit 66 can display multiple selection buttons 92A to 92H and a comparison button 94 on the display screen 72 of the display unit 68. The symbol 92 is used for a general description of the selection buttons, while the symbols 92A to 92H are used for descriptions of individual selection buttons. Selection buttons 92A to 92H are used to select information stored in storage areas 81A to 81H, respectively. Each of the storage areas 81A to 81H has a storage area name of memory#0 to memory#7. Therefore, storage area names such as memory#0 to memory#7 can be displayed on each selection button 92A to 92H.

[0069] The operator can select the information stored in the storage area 81A by clicking the selection button 92A. Here, a case where the above-mentioned reference information 97A is stored in the storage area 81A is described as an example. When the selection button 92A is clicked, information for identifying the information stored in the storage area 81A, specifically, the date and time when the information was acquired, and the like, is displayed on the display screen 72. Further, the operator can select the information stored in the storage area 81B by clicking the selection button 92B. Here, a case where the above-mentioned comparison information 97B is stored in the storage area 81B is described as an example. When the selection button 92B is clicked, information for identifying the information stored in the storage area 81B, specifically, the date and time when the information was acquired, and the like, is displayed on the display screen 72. When the selection buttons 92 are clicked, the display control section 66 performs emphasized display on the clicked selection button 92. After the plurality of selection buttons 92 are clicked, the operator clicks the comparison button 94. When the comparison button 94 is clicked, the comparison section 62 compares the information stored in the selected storage areas 81. Here, as described above, the storage area 81A and the storage area 81B are selected. Thus, the comparison section 62 compares the information stored in the storage area 81A with the information stored in the storage area 81B.

[0070] Figure 6 An example of a display for indicating the comparison result. As shown in Figure 6 the display control section 66 can display the comparison result given by the comparison section 62 on the display screen 72 of the display section 68. Figure 6 An example where the comparison result of the reference information 97A stored in the storage area 81A and the comparison information 97B stored in the storage area 81B is displayed is shown in FIG. 9. As described above, the storage area name of the storage area 81A in which the reference information 97A is stored is memory #0. Thus, the storage area name 96A corresponding to the storage area 81A, that is, memory #0, is displayed on the display screen 72 of the display section 68. The reference information 97A stored in the storage area 81A is displayed below the storage area name 96A (memory #0). As described above, the storage area name of the storage area 81B in which the comparison information 97B is stored is memory #1. Thus, the storage area name 96B corresponding to the storage area 81B, that is, memory #1, is displayed on the display screen 72 of the display section 68. The comparison information 97B stored in the storage area 81B is displayed below the storage area name 96B (memory #1). In this way, the display control section 66 can display the reference information 97A together with the comparison information 97B on the display screen 72 of the display section 68.

[0071] The display control section 66 can display information in which a difference between the reference information 97A and the comparison information 97B exceeds the difference threshold on the display screen 72 of the display section 68 in a manner that is distinguishable. In Figure 6 In the example shown, the information in which a difference between the reference information 97A and the comparison information 97B exceeds the difference threshold in the comparison information 97B is the material-related information 79C of the workpiece W, the information 79G indicating the person in charge, the machining current-related information 85B, the machining speed-related information 85C, the machining date and time-related information 85H, the size-related information 87A, and the surface roughness-related information 87C. Thus, in the example shown, these pieces of information in the comparison information 97B are displayed in a distinguishable manner. Figure 6 In the example shown, these pieces of information in the comparison information 97B are displayed in a distinguishable manner. Figure 6 Examples in which information is displayed in a distinguishable manner by means of hollow characters are shown in the foregoing, but are not limited thereto. Information can also be displayed in a distinguishable manner by making the display colors of the characters different. Furthermore, information can also be displayed in a distinguishable manner by making the characters flash, or the like.

[0072] Note that the foregoing describes an example in which information in which a difference between the reference information 97A and the comparison information 97B exceeds the difference threshold in the comparison information 97B is displayed in a distinguishable manner on the display screen 72 of the display section 68, but is not limited thereto. Information in which a difference between the reference information 97A and the comparison information 97B exceeds the difference threshold can also be displayed on the display screen 72 of the display section 68. That is, information in which a difference between the reference information 97A and the comparison information 97B does not exceed the difference threshold can not be displayed on the display screen 72 of the display section 68, and only information in which a difference between the reference information 97A and the comparison information 97B exceeds the difference threshold can be displayed on the display screen 72 of the display section 68. In this case, only information in which a difference between the reference information 97A and the comparison information 97B exceeds the difference threshold is displayed on the display screen 72 of the display section 68, so there is no need to display information in a distinguishable manner.

[0073] The display control section 66 can display a radar chart on the display screen 72 of the display section 68 that indicates changes in the comparison information 97B relative to the reference information 97A. Figure 7A and Figure 7B A diagram showing an example of a radar chart. Figure 7A A radar chart 96 in which each of the items p1 to p10 is 100% is shown in the foregoing. This radar chart 96 corresponds to the contents of the reference information 97A. Figure 7BAn example of a radar chart 96 showing a variation of comparative information 97B with respect to reference information 97A is shown. Pl to p7 correspond to each item of the in-process information 85. Specifically, pl corresponds to, for example, a processing voltage. Further, p2 corresponds to, for example, a processing current. Further, p3 corresponds to, for example, a processing speed. Further, p4 corresponds to, for example, a processing temperature. Further, p5 corresponds to, for example, a processing hydraulic pressure. Further, p6 corresponds to, for example, a specific resistance. Further, p7 corresponds to, for example, a processing time. P8 to p10 correspond to each item of the processing result information 87. Specifically, p8 corresponds to, for example, a size. P9 corresponds to, for example, a straightness. P10 corresponds to, for example, a surface roughness.

[0074] For example, in a case where a variation of the processing voltage is, for example, less than ±1%, pl is not reduced. That is, in a case where a variation of the processing voltage is, for example, less than ±1%, pl is set to 100%. In a case where a variation of the processing voltage is, for example, ±1% or more and less than ±2%, pl is reduced by, for example, Al% with respect to 100%. In a case where a variation of the processing voltage is, for example, ±2% or more and less than ±3%, pl is reduced by, for example, A2% with respect to 100%. In a case where a variation of the processing voltage is, for example, ±3% or more and less than ±4%, pl is reduced by, for example, A3% with respect to 100%. In a case where a variation of the processing voltage is, for example, ±4% or more, pl is reduced by, for example, A4% with respect to 100%. A2 is greater than Al, A3 is greater than A2, and A4 is greater than A3.

[0075] For example, in a case where a variation of the processing current is, for example, less than ±1%, p2 is not reduced. In a case where a variation of the processing current is, for example, ±1% or more and less than ±2%, p2 is reduced by, for example, Bl% with respect to 100%. In a case where a variation of the processing current is, for example, ±2% or more and less than ±3%, p2 is reduced by, for example, B2% with respect to 100%. In a case where a variation of the processing current is, for example, ±3% or more and less than ±4%, p2 is reduced by, for example, B3% with respect to 100%. In a case where a variation of the processing current is, for example, ±4% or more, p2 is reduced by, for example, B4% with respect to 100%. B2 is greater than Bl, B3 is greater than B2, and B4 is greater than B3.

[0076] For example, in the case where the variation in the processing speed is, for example, not more than ±2%, p3 is not decreased. In the case where the variation in the processing speed is, for example, more than ±2% and not more than ±4%, p3 is decreased by, for example, C1% with respect to 100%. In the case where the variation in the processing speed is, for example, more than ±4% and not more than ±6%, p3 is decreased by, for example, C2% with respect to 100%. In the case where the variation in the processing speed is, for example, more than ±6% and not more than ±8%, p3 is decreased by, for example, C3% with respect to 100%. In the case where the variation in the processing speed is, for example, more than ±8%, p3 is decreased by, for example, C4% with respect to 100%. C2 is larger than C1, C3 is larger than C2, and C4 is larger than C3.

[0077] For example, in the case where the variation in the processing temperature is, for example, not more than ±1%, p4 is not decreased. In the case where the variation in the processing temperature is, for example, more than ±1% and not more than ±2%, p4 is decreased by, for example, D1% with respect to 100%. In the case where the variation in the processing temperature is, for example, more than ±2% and not more than ±3%, p4 is decreased by, for example, D2% with respect to 100%. In the case where the variation in the processing temperature is, for example, more than ±3% and not more than ±4%, p4 is decreased by, for example, D3% with respect to 100%. In the case where the variation in the processing temperature is, for example, more than ±4%, p4 is decreased by, for example, D4% with respect to 100%. D2 is larger than D1, D3 is larger than D2, and D4 is larger than D3.

[0078] For example, in the case where the variation in the processing hydraulic pressure is, for example, not more than ±2%, p5 is not decreased. In the case where the variation in the processing hydraulic pressure is, for example, more than ±2% and not more than ±4%, p5 is decreased by, for example, E1% with respect to 100%. In the case where the variation in the processing hydraulic pressure is, for example, more than ±4% and not more than ±6%, p5 is decreased by, for example, E2% with respect to 100%. In the case where the variation in the processing hydraulic pressure is, for example, more than ±6% and not more than ±8%, p5 is decreased by, for example, E3% with respect to 100%. In the case where the variation in the processing hydraulic pressure is, for example, more than ±8%, p5 is decreased by, for example, E4% with respect to 100%. E2 is larger than E1, E3 is larger than E2, and E4 is larger than E3.

[0079] For example, in a case where the variation in the specific resistance of the processing liquid is, for example, not more than ±3%, p6 is not decreased. In a case where the variation in the specific resistance of the processing liquid is, for example, more than ±3% and not more than ±6%, p6 is decreased by, for example, F1% with respect to 100%. In a case where the variation in the specific resistance of the processing liquid is, for example, more than ±6% and not more than ±9%, p6 is decreased by, for example, F2% with respect to 100%. In a case where the variation in the specific resistance of the processing liquid is, for example, more than ±9% and not more than ±12%, p6 is decreased by, for example, F3% with respect to 100%. In a case where the variation in the specific resistance of the processing liquid is, for example, more than ±12%, p6 is decreased by, for example, F4% with respect to 100%. F2 is greater than F1, F3 is greater than F2, and F4 is greater than F3.

[0080] For example, in a case where the variation in the processing time is, for example, not more than ±1%, p7 is not decreased. In a case where the variation in the processing time is, for example, more than ±1% and not more than ±2%, p7 is decreased by, for example, G1% with respect to 100%. In a case where the variation in the processing time is, for example, more than ±2% and not more than ±3%, p7 is decreased by, for example, G2% with respect to 100%. In a case where the variation in the processing time is, for example, more than ±3% and not more than ±4%, p7 is decreased by, for example, G3% with respect to 100%. In a case where the variation in the processing time is, for example, more than ±4%, p7 is decreased by, for example, G4% with respect to 100%. G2 is greater than G1, G3 is greater than G2, and G4 is greater than G3.

[0081] For example, in a case where the variation in the size is, for example, not more than ±1%, p8 is not decreased. In a case where the variation in the size is, for example, more than ±1% and not more than ±2%, p8 is decreased by, for example, H1% with respect to 100%. In a case where the variation in the size is, for example, more than ±2% and not more than ±3%, p8 is decreased by, for example, H2% with respect to 100%. In a case where the variation in the size is, for example, more than ±3% and not more than ±4%, p8 is decreased by, for example, H3% with respect to 100%. In a case where the variation in the size is, for example, more than ±4%, p8 is decreased by, for example, H4% with respect to 100%. H2 is greater than H1, H3 is greater than H2, and H4 is greater than H3.

[0082] For example, in a case where the variation in straightness is, for example, not more than ±1%, p9 is not reduced. In a case where the variation in straightness is, for example, more than ±1% and not more than ±2%, p9 is reduced by, for example, I1% with respect to 100%. In a case where the variation in straightness is, for example, more than ±2% and not more than ±3%, p9 is reduced by, for example, I2% with respect to 100%. In a case where the variation in straightness is, for example, more than ±3% and not more than ±4%, p9 is reduced by, for example, I3% with respect to 100%. In a case where the variation in straightness is, for example, more than ±4%, p9 is reduced by, for example, I4% with respect to 100%. I2 is larger than I1, I3 is larger than I2, and I4 is larger than I3.

[0083] For example, in a case where the variation in surface roughness is, for example, not more than ±1%, p10 is not reduced. In a case where the variation in surface roughness is, for example, more than ±1% and not more than ±2%, p10 is reduced by, for example, J1% with respect to 100%. In a case where the variation in surface roughness is, for example, more than ±2% and not more than ±3%, p10 is reduced by, for example, J2% with respect to 100%. In a case where the variation in surface roughness is, for example, more than ±3% and not more than ±4%, p10 is reduced by, for example, J3% with respect to 100%. In a case where the variation in surface roughness is, for example, more than ±4%, p10 is reduced by, for example, J4% with respect to 100%. J2 is larger than J1, J3 is larger than J2, and J4 is larger than J3.

[0084] It is possible to grasp which item has a substantial difference according to the radar chart 96. In addition, it is possible to grasp the degree of the difference in each item according to the radar chart 96.

[0085] Note that, in the above, the case where p1 to p10 are reduced by the degree predetermined for each range in a case where the variation in the value of each item is within the range is described as an example, but the present technology is not limited to this. It is also possible to directly express the variation in the value of each item on the radar chart.

[0086] The comparison section 62 can calculate the degree of similarity Y according to the comparison between the reference information 97A and the comparison information 97B. The degree of similarity Y can be calculated by, for example, the following formula (1).

[0087] Y [%] = 100 - (A + B + C + D + E + F + G + H + I + J)... (1)

[0088] A corresponds to a decrease in p1 described above. B corresponds to a decrease in p2 described above. C corresponds to a decrease in p3 described above. D corresponds to a decrease in p4 described above. E corresponds to a decrease in p5 described above. F corresponds to a decrease in p6 described above. G corresponds to a decrease in p7 described above. H corresponds to a decrease in p8 described above. I corresponds to a decrease in p9 described above. J corresponds to a decrease in p10 described above. Further, in a case where A+B+C+D+E+F+G+H+I+J is equal to or greater than 100, Y=0 is set.

[0089] The display control section 66 can display the similarity calculated by the comparison section 62 as described above on the display screen 72 of the display section 68. Figure 8 A diagram for an example of display of the similarity. Figure 8 An example in a case where the similarity is 95% is shown in FIG. 9. In this example, the similarity is displayed on the pop-up screen 98. The pop-up screen 98 can display a close button 100. When the close button 100 is clicked, the display control section 66 ends the display of the pop-up screen 98. Figure 8 An example shown in FIG. 9, the similarity is displayed on the pop-up screen 98. The pop-up screen 98 can display a close button 100. When the close button 100 is clicked, the display control section 66 ends the display of the pop-up screen 98.

[0090] As described above, the table 82 is provided in the storage section 58. Figure 9 A diagram for an example of the table. In the table 82, a site that needs maintenance or confirmation is specified in accordance with the difference between the reference information 97A and the comparison information 97B. The determination section 64 can determine the site that needs maintenance or confirmation from the difference between the reference information 97A and the comparison information 97B and the table 82. The display control section 66 can display information indicating the site that needs maintenance or confirmation on the display screen 72 of the display section 68 in accordance with the determination result given by the determination section 64. For example, in a case where the difference between the reference information 97A and the comparison information 97B is the processing current, it can be that the line has deteriorated or the like. Therefore, in a case where the difference between the reference information 97A and the comparison information 97B is the current, the line and the like are described as the site that should be maintained or confirmed in the table 82, for example. In a case where the difference between the reference information 97A and the comparison information 97B is the processing current, for example, the line is displayed as the site that needs maintenance or confirmation, so it is possible to contribute to the convenience of maintenance and the like.

[0091] As Figure 2As shown, the control device 18 can communicate with an information management device 88 via the communication section 86. The information management device 88 manages information supplied from a plurality of processing machines 10. Information indicating a comparison result and the like can be transmitted to an external device 90 via the communication section 86 and the information management device 88. The communication between the information management device 88 and the external device 90 can be performed via a network 93 such as the Internet. The external device 90 is, for example, a device of a company that provides a maintenance service for the processing machine 10. That is, the external device 90 is, for example, a device of a support party 91. As the external device 90, a server, a mobile terminal, a personal computer, and the like can be exemplified, but are not limited thereto. As the mobile terminal, a smartphone, a tablet terminal, and the like can be exemplified, but are not limited thereto.

[0092] Next, the processing machine of the present embodiment is described. Figure 10 The operation of the processing machine of the present embodiment is described. Figure 10 A flowchart showing the operation of the processing machine of the present embodiment is shown. Figure 10 The operation at the time of inspection processing performed after the acquisition of the reference information 97A is shown in FIG. 8. The reference information 97A has been stored in the information storage section 80.

[0093] In step S1, arrangement for performing inspection processing is performed. At the time of arrangement, input of arrangement information 79 is performed by an operator. The acquisition section 60 acquires the arrangement information 79 input by the operator, and stores the acquired arrangement information 79 to the information storage section 80. Thereafter, the process proceeds to step S2.

[0094] In step S2, inspection processing is performed. The inspection processing can be started by the operator pressing an unillustrated start switch or the like. The acquisition section 60 acquires a plurality of processing-in-progress information 85 indicating the processing state at the time of performing inspection processing on the processing target object W. The acquisition section 60 stores the acquired processing-in-progress information 85 to the information storage section 80. Thereafter, the process proceeds to step S3.

[0095] In step S3, the processing object obtained by the inspection processing is measured using a measuring device. The processing result information 87 obtained by measuring the processing object is input by the operator. The acquisition section 60 acquires the processing result information 87 input by the operator, and stores the acquired processing result information 87 to the information storage section 80. In this way, the arrangement information 79, the processing-in-progress information 85, and the processing result information 87 are stored to the information storage section 80 as comparison information 97B. Thereafter, the process proceeds to step S4.

[0096] In step S4, the comparison section 62 compares the comparison information 97B with the reference information 97A. Thereafter, the process proceeds to step S5.

[0097] In step S5, the display control section 66 displays the comparison result given by the comparison section 62 on the display screen 72 of the display section 68. Thus, Figure 10 The processing shown is completed.

[0098] Thus, according to the present embodiment, information including a plurality of in-process information 85 indicating a processing state at the time of inspection processing on a processing target W and processing result information 87 obtained by measuring a processed product obtained by the inspection processing is stored as reference information 97A to the storage section 58. Then, the comparison information 97B including a plurality of in-process information 85 and processing result information 87 in the inspection processing performed after the inspection processing in which the reference information 97A is acquired is acquired by the acquisition section 60. Then, the comparison result of the comparison information 97B and the reference information 97A is displayed on the display screen 72 of the display section 68. Therefore, according to the present embodiment, the result of periodic inspection or the like can be evaluated with certainty.
