Description

[Technical field]

[0001] The present invention relates to a processing device that processes a workpiece, and a control method for a processing system including the processing device. [Background technology]

[0002] As a machining device, if chips and coolant generated during machining of a workpiece accumulate, problems can occur such as the chips getting caught when the spindle grips the tool, causing errors and machining defects. To continue machining while maintaining machining accuracy, it is necessary to prevent chips from accumulating on the ATC magazine or on the workpiece by cleaning during and after machining, as well as periodically cleaning the milling machine.

[0003] Furthermore, when performing processing that generates sharp chips such as metal chips, more careful cleaning operations are essential to prevent the user from being injured when changing disks or tools. [Prior art documents] [Patent documents]

Embodiments for Carrying Out the Invention

[0009] Embodiments will be described with reference to the drawings. First, the overall configuration of the processing system 1 of the present embodiment will be described with reference to FIGS. 1 and 2.

[0010] [Processing System] The processing system 1 includes a processing device 200 and a coolant supply device 210. The processing device 200 performs processing of a workpiece by a tool within a processing area 120. The processing device 200 houses a processing machine 100 within an exterior cover 101 as a housing. That is, the exterior cover 101 has a spindle, a tool magazine, etc., which will be described later, arranged inside. An openable and closable door (not shown) is provided at the front side opening of the exterior cover 101. The door can access the inside of the housing, that is, the processing area 120 to be described later, enabling the replacement of the workpiece and the manual replacement of the tool.

[0011] The coolant supply device 210 is a device that supplies a coolant, which is a liquid for cooling the workpiece, tool, etc., into the processing area 120 of the processing device 200. The coolant supply device 210 of the present embodiment is arranged below the processing device 200 and has a tank 211, a pump 212, a flow meter 213, a solenoid valve 214, etc., which are connected by pipes 220 to 224. Also, the arrows shown in FIGS. 1 and 2 indicate the path and direction in which the coolant flows. The tank 211 stores the coolant, and the pump 212 sucks out the coolant from the tank 211 through the pipe 220 and sends it into the pipe 221. The coolant sent into the pipe 221 passes through the flow meter 213 via the pipe 222. The flow meter 213 measures the flow rate of the coolant supplied from the pump 212 and transmits a signal to a CPU 85 (FIG. 4), which is the main control unit of the processing system 1 to be described later. A strainer 215 is provided in the middle of the pipe 222 to remove foreign substances in the pipe path.

[0012] The coolant liquid that has passed through the flow meter 213 is sent to the pipe 223 and reaches the solenoid valve 214 provided in the pipe 223. The solenoid valve 214 opens and closes the flow path and is controlled by the above-mentioned CPU 85 to supply and stop the coolant liquid to the processing device 200. The pipe 223 is connected to the processing device 200, and the coolant liquid that has passed through the open solenoid valve 214 is supplied into the processing area 120 through the coolant discharge part 202 as the coolant supply part provided in the spindle head 201 of the processing device 200. When the solenoid valve 214 is in the closed state, the coolant liquid supplied from the pump 212 branches off from the pipe 221 and is returned to the tank 211 through the pipe 224.

[0013] The coolant discharge part 202 is, for example, a nozzle provided around the spindle 11 (FIG. 3) of the spindle head 201, and by discharging the coolant liquid downward, the coolant liquid is supplied toward the tool held by the spindle 11 or the workpiece which is the object to be processed. The coolant liquid supplied from the coolant discharge part 202 accumulates in the lower part of the processing area 120 and is discharged from the lower part of the processing device 200. A tray 216 is provided below the processing device 200 to receive the coolant liquid discharged from the processing device 200 and return it to the tank 211. Thus, in the processing system 1 of the present embodiment, the coolant liquid is used to cool the tool and the workpiece during processing. In the present embodiment, an air blow part 87 (FIG. 4) for blowing air onto the tool or the like is provided.

[0014] [Processing Machine] Next, the processing machine 100 disposed inside the exterior cover 101 of the processing apparatus 200 will be described with reference to FIG. 3. The processing machine 100 includes a frame 1xz as a moving mechanism support member, a first moving mechanism (Z-axis moving mechanism) 10, a second moving mechanism (X-axis moving mechanism) 20, and a third moving mechanism (Y-axis moving mechanism) 30 each supported by the frame 1xz, a support mechanism 40 for supporting a workpiece W as a processing object, a first rotating mechanism (rotating device) 50 and a second rotating mechanism 60 as rotating means for rotatably supporting the support mechanism 40, a tool magazine 70, and an electrical equipment unit 80. The first moving mechanism 10, the second moving mechanism 20, and the third moving mechanism 30 constitute a moving device 100A as a moving means for relatively moving the spindle 11 and the holding device 41, which will be described later, in the three-axis directions of X, Y, and Z.

[0015] The first moving mechanism 10 is supported by the first frame portion 3 of the frame 1xz via the second moving mechanism 20 and is capable of moving the spindle 11 in the Z-axis direction (vertical direction, first direction). A tool 12 is detachably attached to the spindle 11 via a tool holder 12a. That is, the spindle 11 can hold the tool 12. The spindle 11 is rotationally driven by a motor 13. The first moving mechanism 10 has a motor 14 and a guide shaft (not shown) disposed in the Z-axis direction, and reciprocates (moves up and down) the spindle 11 in the Z-axis direction along the guide shaft by driving the motor 14. The spindle 11 is movably supported by the guide shaft via a Z-axis support member (not shown). The guide shaft and the Z-axis support member are covered by a cover 17.

[0016] The second moving mechanism 20 as a moving part is supported by the first frame part 3 of the frame 1xz, and can move the spindle 11 together with the first moving mechanism 10 in the X-axis direction (predetermined direction, horizontal direction, second direction) orthogonal to the Z-axis direction. The second moving mechanism 20 includes a motor 21, a guide shaft 22 arranged in the X-axis direction, and rails 23 and 24 arranged in the X-axis direction. When the motor 21 is driven, the first moving mechanism 10 is reciprocally moved in the X-axis direction along the guide shaft 22. Specifically, the guide shaft 22 which is a screw shaft is inserted into a nut member 19 fixed to a holding part 18 that holds the spindle 11 and the first moving mechanism 10. Further, engaging parts 25 and 26 that engage with the rails 23 and 24 are provided on the holding part 18. When the guide shaft 22 rotates by the motor 21, the nut member 19 screwed with the guide shaft 22 moves along the guide shaft 22. Then, the holding part 18 to which the nut member 19 is fixed and the spindle 11 and the first moving mechanism 10 held by the holding part 18 move in the X-axis direction based on the engagement between the engaging parts 25 and 26 and the rails 23 and 24. The second frame part 4 is connected so as to extend in the Y-axis direction from the lower end part of the first frame part 3, and the first frame part 3 and the second frame part 4 are further connected by a reinforcing plate 29.

[0017] The third moving mechanism 30 is supported by the lower surface of the second frame part 4 of the frame 1xz, and can move the support mechanism 40 in the Y-axis direction (horizontal direction, third direction) orthogonal to the Z-axis direction and the X-axis direction. The third moving mechanism 30 includes a motor 32 and a guide shaft (not shown) arranged in the Y-axis direction. When the motor 32 is driven, the support mechanism 40 is reciprocally moved in the Y-axis direction along the guide shaft. As shown in FIG. 3, the side of the gantry 2 on the support mechanism 40 side in the Y-axis direction is open. And the third moving mechanism 30 can move the support mechanism 40 in the Y-axis direction together with the second rotating mechanism 60 and the first rotating mechanism 50 as will be described in detail later.

[0018] The support mechanism 40 supports a workpiece W as an object to be machined that is machined by a tool 12 such as a dental prosthesis. The holding device 41 as a holding part for holding the workpiece W becomes a disk jig 405 or a block jig 407 depending on the object to be machined. Such a support mechanism 40 has a holding device 41 as a holding part for holding the workpiece W, and a support part 42 whose both ends are respectively connected to the rotating part 51 of the first rotating mechanism 50 and that supports the workpiece W via the holding device 41.

[0019] The first rotating mechanism 50 as a pivoting device is rotatable about an a-axis as a rotation axis orthogonal to the Z-axis direction of the support mechanism 40. In the present embodiment, the a-axis is parallel to the X-axis direction. FIG. 3 shows a state in which the a-axis is tilted to a standby angle of +20°. Such a first rotating mechanism 50 has a support frame 53 that rotatably supports the rotating part 51, and a motor that rotationally drives the rotating part 51. The support frame 53 is formed in a substantially U-shape so as to surround the support mechanism 40, and includes a first support part 53a that supports the motor and the rotating part 51 on one side (driving side), a second support part 53b that supports the rotating part on the other side (driven side), and a connecting part 53c that connects the first support part 53a and the second support part 53b.

[0020] The rotating part 51 supported by the first support part 53a and the rotating part supported by the second support part 53b are arranged so as to face each other in the a-axis direction and be rotatable about the a-axis as a rotation axis. And both ends in the a-axis direction of the support mechanism 40 are respectively supported by the rotating parts on both sides. Thereby, the first rotating mechanism 50 supports the support mechanism 40 so as to be rotatable about the a-axis (X-axis).

[0021] The first rotating mechanism 50 is rotatable by at least 180° and can reverse the front and back of the workpiece W supported by the support mechanism 40. In the present embodiment, the first rotating mechanism 50 can rotate the support mechanism 40 360° about the a-axis. Specifically, as shown in FIG. 8(1), the a-axis can be rotated from -180° to 180°.

[0022] The second rotation mechanism 60 is rotatable about a b-axis, which is another rotation axis orthogonal to the Z-axis and the a-axis, with the support mechanism 40 as the center. In the present embodiment, the b-axis is parallel to the Y-axis direction. Such a second rotation mechanism 50 has a rotating part to which the support frame 53 of the first rotation mechanism 50 is attached, and a motor that rotationally drives the rotating part. The rotating part has a connecting part 53c of the support frame 53 attached thereto, and is rotationally driven by the motor to enable the support frame 53 to rotate about the b-axis.

[0023] The tool magazine 70 as a tool holding part can store a plurality of tools and is arranged adjacent to the first rotation mechanism 50. The tool magazine 70 is movable in the Y-axis direction together with the support mechanism 40 and the like by the third moving mechanism 30. However, even when the support mechanism 40 rotates about the a-axis, the tool magazine 70 does not rotate, and even when the support mechanism 40 rotates about the b-axis, the tool magazine 70 does not rotate.

[0024] In the tool magazine 70, a plurality of types of tools integrally formed with the tool holders 12a are held and arranged in a plurality of rows along the Y-axis direction. And the tool attached to the spindle 11 can be exchanged.

[0025] Also, in the present embodiment, before and after tool storage and removal, by bringing the tip of the tool 12 into contact with the touch sensor 96 as a tip detection means capable of detecting the tip of the tool 12 gripped by the spindle 11, an operation is performed to confirm whether the tool 12 is gripped by the spindle 11.

[0026] The electrical equipment unit 80 is attached inside the frame 1xz. That is, the electrical equipment unit 80 is arranged above the second frame part 4 on the side opposite to the side where the first moving mechanism 10 of the first frame part 3 is supported. Such an electrical equipment unit 80 controls the processing system 1 or the processing device 200, and has a control board for controlling the driving of the spindle and the motors of each axis, and a plurality of control parts that calculate the pulses output to the motors from the signals of the rotary encoders of the corresponding motors and appropriately control the rotation of the corresponding motors.

[0027] Further, the processing machine 100 of the present embodiment is an NC processing device that performs automatic processing under computer control. Specifically, machining data is created by a CAD / CAM system using an external device 800 such as a personal computer, and based on this data, the workpiece W is machined by numerical control. For this purpose, an external device 800 such as a personal computer that issues commands to the processing machine 100 is connected to the processing machine 100. Note that a computer equipped with a CPU and a memory capable of numerical control may be provided in the processing machine 100 itself. The control means described later may be provided in either the processing device or the computer connected to the processing device.

[0028] For example, when creating a dental prosthesis (dental material) using the processing machine 100, the data of the dental prosthesis measured by a three-dimensional measuring instrument is transferred to a CAD / CAM system, and machining data is created by the CAD / CAM system. Then, based on this machining data, the processing machine 100 is controlled to cut the workpiece W with the tool 12, thereby creating a dental prosthesis.

[0029] Next, the control configuration in the electrical unit 80 will be described with reference to FIG. 4. The electrical unit 80 includes a CPU 85 which is a control means (main control unit), input / output ports (I / O) 86i, control units 84x, 84y, 84z for each motor, a control unit 84c for the spindle, a control unit 84a for the a-axis, a control unit 84b for the b-axis, and the like. The CPU 85 performs various calculations using the memory 86m based on the input data and signals, and transmits instructions for the rotation speed and position to the control units 84x, 84y, 84z, 84a, 84b, 84c serving as connected servo amplifiers.

[0030] The I / O86i is connected to the compressor 350, the pump 212, the touch sensor 96, the air pressure detection sensor 91, the flow meter 213, and the solenoid valve 214. The compressor 350 supplies air to the air blow part 87 of the processing device 200. The air blow part 87 blows the air supplied from the compressor 350 onto the tool 12 attached to the main shaft 11 to cool the tool 12 and remove the chips adhering to the tool 12. The pressure of the air supplied to the air blow part 87 is detected by the air pressure detection sensor 91, and the detection signal of the air pressure detection sensor 91 is sent to the CPU85 via the I / O86i.

[0031] As described above, the pump 212 supplies the coolant liquid to the coolant discharge part 202. The coolant discharge part 202 supplies the coolant liquid toward the tool 12 and the workpiece. The touch sensor (tool length sensor) 96 as the tip detection means is used not only to confirm whether the tool 12 is gripped by the main shaft 11 during the tool change operation as described above, but also to detect the length of the tool 12 and send a signal to the CPU85.

[0032] The control parts 84x, 84y, 84z of the respective motors provided in the CPU85 drive the X, Y, and Z motors based on commands from the CPU85. Encoders are provided in the respective motors 21, 32, 14 as position detection means. The encoder detects, for example, the number of rotations, the rotation angle, and the rotation direction of the rotation shaft of each of the motors 21, 32, 14. Then, the amount by which each of the stages x, y, z has actually moved (the actual position, the relative position with respect to the holding device 41 of the main shaft 11) is detected by the driving of each of the motors 21, 32, 14.

[0033] The main shaft control part 84c controls a motor (not shown) that rotates the main shaft 11 to control the rotation speed of the main shaft (spindle). Also, the control parts 84a, 84b of the a and b axes drive the motors 54, 62 of the a and b axes based on commands from the CPU85. Encoders 54a, 62a are also provided in these motors 54, 62, and the rotation angles around the a and b axes of the support mechanism 40 can be detected.

[0034] By controlling each part of the processing machine 100 with the CPU 85 in this way, predetermined processing is performed on the workpiece W held as described above. Each operation and process described later is executed by the CPU 85 developing a program in a storage means such as the memory 86m.

[0035] The cleaning mode of the processing apparatus in the present embodiment will be described below. By discharging the coolant liquid from the coolant discharge unit 202 onto the workpiece W and blowing air from the air blow unit 87 onto the workpiece W, the chips adhering to the workpiece W can be removed.

[0036] The operation of the cleaning mode is executed by a predetermined M code, such as M30, in the executed NC file. When the cleaning mode is executed during processing, first, as a preliminary operation for the cleaning operation, the current coordinate position is stored in the memory 86m as the return coordinate position. The control unit 84 raises the spindle 11, separates the tool from the object to be processed, stops the rotation of the spindle 11, and after performing control to move the spindle 11 to a position above the tool magazine 70, the tool 12 is stored in the tool magazine 70.

[0037] As will be described later, when an NC file indicating that the holding device 41 holds the disk jig 405 is executed, S403 is executed, and the control unit 84z raises and separates the spindle 11 from the height where the tool 12 is stored, and the control units 84x and 84y move the spindle 11 to the cleaning operation start point of the disk jig 405.

[0038] The control unit 84z lowers the spindle 11 to the height at which the coolant liquid is sprayed and starts discharging the coolant liquid. The spindle 11 is moved as shown by the locus (arrow) 406 in FIG. 6 to clean the disk fixing portion on the disk jig 405 and the workpiece W with the coolant liquid. When the spindle 11 is moved to the cleaning operation end point of the disk jig 405, the discharge of the coolant liquid is stopped, and the control unit 84z raises the spindle 11.

[0039] The control unit 84z lowers the spindle 11 to a height where air is blown and starts the discharge of the air blow. While blowing air at the maximum flow rate within the possible range, the spindle 11 is moved as shown by the locus (arrow) 406 in FIG. 6 to blow off the coolant liquid on the disk fixing portion on the disk jig 405 and the workpiece W. When the spindle 11 is moved to the end point of the cleaning operation of the disk jig 405, the air blow is stopped, the control unit 84z raises the spindle 11, and the cleaning mode is terminated.

[0040] As will be described later, when an NC file indicating that the holding device 41 holds the block jig 407 is executed, S404 is executed. The control unit 84z raises and releases the spindle 11 from the height where the tool 12 is stored, and the control units 84x and 84y move the spindle 11 to the start point of the cleaning operation of the block jig 407.

[0041] The control unit 84z lowers the spindle 11 to a height where the coolant liquid is blown and starts the discharge of the coolant liquid. The spindle 11 is moved along the block material fixing portion on the jig and the workpiece W as shown by the locus (arrow) 408 in FIG. 7 to clean the block jig 407 and the workpiece W with the coolant liquid. When the spindle 11 is moved to the end point of the cleaning operation of the block jig 407, the discharge of the coolant liquid is stopped, and the control unit 84z raises the spindle 11.

[0042] The control unit 84z lowers the spindle 11 to a height where air is blown and starts the discharge of the air blow. While blowing air at the maximum flow rate within the possible range, the spindle 11 is moved as shown by the locus (arrow) 408 in FIG. 7 to blow off the coolant liquid accumulated on the block material fixing portion on the block jig 407 and the workpiece W. When the spindle 11 is moved to the end point of the cleaning operation of the block jig 407, the air blow is stopped, the control unit 84z raises the spindle 11, and the cleaning mode is terminated.

[0043] In the above-described embodiment, NC data is read and the jig is determined. However, in addition to the NC data, it may be possible to determine which of the disk jig 405 and the block jig 407 is attached by the settings of the processing device or the sensor.

[0044] Fig. 5 shows a flowchart of the automatic determination control of the jig according to the embodiment of the present invention. An example of an NC file is illustrated in Table 1. [Table 1]

[0045] First, at S401, at the start of machining, search for a line written with CECOMMENT at the beginning of the comment line of the NC file, read the character string indicating the jig type, and confirm by comparing and referring to whether it exists in the table stored in the memory 86m as the storage means. At this time, a disk is stored in the table of the memory 86m. At S402, it is determined whether there is a character indicating a disk in the jig type.

[0046] If there is a character indicating a disk in the jig type, execute S403, enable the disk cleaning mode, and start machining. Since the disk processes a single workpiece, chips may scatter to an area where machining is not being performed. At the end of machining, move the spindle as shown by the locus (arrow) 406 in Fig. 6 so that the chips flow down from top to bottom, and clean the periphery of the disk jig and the entire workpiece.

[0047] If there is a character indicating a block in the jig type, execute S404, enable the block cleaning mode, and start machining. When the jig is a block, there is a high possibility that chips will scatter to the area where the block material is attached. At the end of machining, move the spindle as shown by the locus (arrow) 408 in Fig. 7, and clean the periphery of the block jig and the workpiece.

[0048] Perform either the cleaning operation of S403 or S404 to end the cleaning mode. As a function of the CPU 85, execute a program developed in the memory 86m as an NC code reading means and a jig comparison means.

[0049] During the execution of the cleaning mode, first discharge the coolant to flush out the chips accumulated during processing. Next, discharge air through the same path to blow away the accumulated coolant, and execute a two-step cleaning operation of coolant and air.

[0050] <Example 1> Next, the processing apparatus according to Example 1 of the present embodiment will be described. FIG. 8 is a view of the jig seen from the inclination direction of the a-axis. FIG. 8(1) is a view in which the a-axis is inclined to 0° as the reference angle with respect to the angle θA.

[0051] After processing the disk or block, rotate the upper surface of the workpiece W of the disk jig 405 or the block jig 407 to the side opposite to the opening / closing door, and execute the cleaning operation.

[0052] The angle θB shown in FIG. 8(2) is a view in which the a-axis is inclined from -15° to -20°. By inclining the upper surface of the workpiece W to the side opposite to the opening / closing door side, it is possible to prevent chips from flying into the light-transmitting window 103 and the tool magazine 70 and chips from entering the gap of the holding device 41. By rotating the disk jig 405 and the block jig 407 and performing the cleaning operation from top to bottom, it is possible to efficiently flush out the chips accumulated on the workpiece.

[0053] <Example 2> Next, the processing apparatus according to Example 2 of the present embodiment will be described. The basic configuration of this example is the same as that of Example 1. Therefore, in the following description, the same reference numerals are used for the same parts, and the description thereof is omitted.

[0054] The angle θC shown in Fig. 8(3) is a view in which the a-axis is inclined by +90° (the first angle). After the disk machining, the a-axis is inclined by +90° so that the end face of the disk jig 405 faces the spindle, and then coolant is discharged. While gradually decreasing the angle of the a-axis toward 0°, a cleaning operation is executed. Note that 0° is merely an example, and any angle (the second angle) smaller than the first angle at which the disk fixing portion faces the spindle may be used.

[0055] In this embodiment, the spindle 11 is moved in the direction opposite to the locus (arrow) 406 in Fig. 6 to perform cleaning between the disk fixing portion on the disk jig 405 and the workpiece W. Since more chips are likely to be generated during disk machining than during block machining, by discharging the coolant after inclining the a-axis by +90°, the chips accumulated in the gap between the support frame connecting portion 53c and the disk jig 405 can be made to fall. Also, by gradually changing the inclination of the a-axis from +90° to 0°, the disk jig 405 and the workpiece W can be cleaned evenly. Further, although the standby angle of the a-axis is +20°, by inclining it to 0°, the chips accumulated in the disk fixing portion can also be cleaned by the coolant discharged from above.

[0056] This control enables continuous machining while maintaining the machining accuracy and can prevent the occurrence of errors caused by chips.

[0057] The present invention is not limited to what has been described above, and various modifications can be applied without departing from the gist of the present invention. For example, in the above-described embodiment, an example of performing a cleaning operation using the type of jig among the processing information was shown. However, if the processing area information is read from the NC data and it is the processing area where the block is placed, the cleaning operation for the block may be executed, and if it is the processing area where the disk is placed, the cleaning operation for the disk may be executed. Also, in the case of a disk, since a large amount of chips scatter in the non-processing area, the processing area information is read from the NC data, and the cleaning operations for the periphery of the disk jig and the non-processing area may be executed. In the case of a block, since chips scatter in the block jig and the processing area, the processing area information is read from the NC data, and the cleaning operations for the periphery of the block jig and the processing area may be executed. Further, the disk used for processing and the usage range of the disk are stored from the NC data, and by reading the usage area for each disk, a cleaning operation suitable for the disk used for processing may be executed.

[0058] Also, the cleaning operation may be executed only when a tool that generates a large amount of chips depending on the tool diameter used for processing is used. Also, regarding the angle of the jig during the cleaning operation, it is not limited to the above-described values, and an angle that can efficiently flow down the chips accumulated on the workpiece from top to bottom may be used. Regarding the block, if there is a gap between the jig and the material, an angle of 0° or a positive angle may be used. Also, regarding the disk, a positive angle that can drop the chips accumulated in the gap between the support frame connecting portion and the jig may be used.
