[0050] It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0051] Reference Figure 1 , Figure 1 is a structural schematic diagram of a machining device of a numerical control machine tool related to a hardware running environment of an embodiment scheme of the application.

The memory 1005 can be a high-speed random access memory (RAM) memory, or a stable non-volatile memory (NVM) such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the machining equipment of the numerical control machine tool, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0054] As Figure 1 As shown in the figure, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a machining program of the numerical control machine tool.

[0055] In Figure 1 As shown in the figure, the network interface 1004 of the machining equipment of the numerical control machine tool is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the machining equipment of the numerical control machine tool can be arranged in the machining equipment of the numerical control machine tool, and the machining program of the numerical control machine tool stored in the memory 1005 is called by the processor 1001 to execute the machining method of the numerical control machine tool provided by the embodiment of the application.

[0056] The embodiment of the application provides a machining method of a numerical control machine tool, which refers to Figure 2 , Figure 2 The figure is a flowchart of the first embodiment of the machining method of the numerical control machine tool.

[0057] The machining method of the numerical control machine tool includes the following steps:

[0058] Step S10: determining the to-be-compensated point and the compensation size and compensation position of the to-be-compensated point according to the compensation measurement result and compensation mode of each processing point.

[0059] It should be noted that the execution subject of the embodiment is a control unit of a numerical control machine tool, and the numerical control machine tool comprises an input unit, an execution unit and the control unit, and can further comprise other functional units or components, which are not limited in the embodiment.

[0060] It can be understood that the compensation measurement result refers to a size measurement result obtained by the control unit through a pre-set automatic measurement program for size measurement of each point in the to-be-processed material, and the compensation mode comprises a measurement mode used when each point is measured. Each point on the material after the first processing of the to-be-processed material is a processing point. The to-be-compensated point refers to a processing point that needs to be automatically compensated, the compensation size refers to a size value that needs to be compensated for the to-be-compensated point, and the compensation position refers to a position of the to-be-compensated point after automatic compensation.

[0061] In a specific implementation, the to-be-compensated point, the compensation size and the compensation position of the to-be-compensated point determined under different compensation modes are different, and the compensation mode comprises but is not limited to single-side measurement in the positive X-axis direction, single-side measurement in the negative X-axis direction, single-side measurement in the positive Y-axis direction, single-side measurement in the negative Y-axis direction, single-side measurement in the positive Z-axis direction, and single-side measurement in the negative Z-axis direction, etc. Other point measurement modes can also be included, which are not limited in the embodiment. When measuring, the measuring head in the numerical control machine tool will make dot measurement according to the point coordinates and the measurement mode, so as to obtain the compensation measurement result of each processing point.

[0062] It should be noted that after the initial processing of the to-be-processed material, the automatic measurement + automatic compensation program is started, and the to-be-compensated point which needs to be compensated is determined according to the compensation measurement result of each processing point obtained by automatic measurement and the compensation mode used when each processing point is measured, and the compensation size and compensation position of the to-be-compensated point are further determined.

[0063] It can be understood that in order to ensure the accuracy and accuracy when performing automatic compensation, further, the to-be-compensated point and the compensation size and compensation position of the to-be-compensated point are determined according to the compensation measurement result and compensation mode of each processing point, comprising: determining the corresponding basic size and tolerance range according to each processing point; determining the to-be-compensated point and the compensation size of the to-be-compensated point according to the compensation measurement result, the basic size, the tolerance range and the measurement mode of each processing point; determining the compensation position according to the compensation size of the to-be-compensated point.

[0064] In a specific implementation, each processing point corresponds to a component structure on the material to be processed, each component structure has a set of basic dimensions and upper and lower limit tolerances, and the upper and lower limit tolerances are the tolerance range. Therefore, when performing automatic compensation, the basic dimensions and tolerance range of each processing point need to be determined according to the processing point. The actual measurement size of each processing point can be determined according to the compensation measurement result of each processing point.

[0065] It should be noted that whether the actual measurement size of each processing point is within the tolerance range of the basic size is determined. If the actual measurement size is within the tolerance range of the basic size, there is no point to be compensated. If the size of the actual measurement size of the processing point exceeds the upper limit tolerance of the basic size, it means that the processing point is overcut and does not need to be compensated, but will be marked as overcut. If the actual measurement size of the processing point is less than the lower limit tolerance of the basic size, it means that the processing is not in place, and compensation is needed for the point. Calculate the difference between the actual measurement size and the lower limit tolerance of the basic size, and determine the compensation size based on the difference and the measurement mode. The compensation size under the single-sided measurement mode and the double-sided measurement mode is not the same. Under single-sided measurement, only single-sided compensation is needed, and under double-sided measurement, double-sided compensation is needed.

[0066] It can be understood that the position of the point to be compensated after compensation can be determined according to the current point coordinates of the point to be compensated and the compensation size, i.e. the compensation position is obtained, and the compensation position of the point to be compensated is defined in the program number. After finding the program number corresponding to the point to be compensated, the compensation position of the point to be compensated is clear.

[0067] In a specific implementation, in order to realize automatic processing and automatic compensation, further, before the step of determining the point to be compensated and the compensation size and compensation position of the point to be compensated according to the compensation measurement result and compensation mode of each processing point, the method further comprises: receiving a numerical control processing instruction; determining a processing type according to the numerical control processing instruction; determining a processing mode according to the processing type; performing preliminary processing according to the processing mode; and after the processing is completed, performing compensation measurement on the plurality of processing points to obtain the compensation measurement result of each processing point.

[0068] It should be noted that the numerical control processing instruction refers to an instruction sent by a technician to start the processing procedure of the material to be processed. The numerical control processing instruction contains the type of processing that needs to be performed on the processing material. The processing type includes but is not limited to fine milling of the bottom surface and fine milling of the side wall. The control unit determines the processing type according to the identification information corresponding to the processing type attached in the numerical control processing instruction after receiving the numerical control processing instruction sent by the technician.

[0069] It can be understood that different processing types correspond to different processing methods, for example, when the processing type corresponds to fine milling of the side wall, the corresponding processing method is to process according to the 0 position. Therefore, after determining the processing type, the corresponding processing method is determined according to the processing type, and the processing material is preliminarily processed according to the processing method. After the preliminary processing is completed, the automatic measurement + automatic compensation program is started to perform the first automatic compensation measurement on each processing point, and the compensation measurement result of each processing point is obtained.

[0070] In a specific implementation, in order to realize accurate processing of the processing material, further, the processing method determined according to the processing type comprises: when the processing type is a bottom surface processing type, obtaining a tool size; determining a processing allowance according to the tool size; and generating a stock allowance processing method according to the processing allowance.

[0071] It should be noted that the bottom surface processing type refers to the processing type of fine milling of the bottom surface. When the processing type is the bottom surface processing type, the size of the tool in the numerical control machine tool is obtained. The size of the tool can be the diameter of the tool or the radius of the tool, and the present embodiment does not limit this. The processing allowance is determined according to the tool size. The processing allowance refers to the processing amount that needs to be reserved when processing. The stock allowance processing method is generated according to the processing allowance, specifically, the stock allowance processing is performed according to the processing allowance.

[0072] Step S20: automatically compensating the to-be-compensated point according to the compensation size and the compensation position, to obtain a plurality of preliminary processing points.

[0073] It should be noted that after the to-be-compensated point is determined according to each processing point, the processing points are divided into to-be-compensated points and points that do not need to be compensated. The preliminary processing point refers to the point that does not need to be compensated and the to-be-compensated point after compensation.

[0074] It can be understood that the automatic compensation program is started to automatically compensate the to-be-compensated point according to the compensation size and the compensation position, to obtain the to-be-compensated point after compensation. The to-be-compensated point after compensation and the points that do not need to be compensated in all processing points jointly constitute a plurality of preliminary processing points.

[0075] Step S30: processing measurement is performed on the plurality of preliminary processing points, and a processing end instruction is generated according to the measurement result of each preliminary processing point.

[0076] It should be noted that after the plurality of preliminary machining points are determined, the size of each preliminary machining point is measured again, the unqualified machining program in the machining process is identified, the preliminary machining point corresponding to the unqualified machining program in the machining process is specified to be machined, after the specified machining is completed, the preliminary machining point after machining is measured again, and when the actual measurement size of the preliminary machining point after machining meets the tolerance range of the basic size, it is determined that the machining result instruction is generated, thereby ending the machining.

[0077] In the embodiment, the compensation measurement result and the compensation mode of each machining point are used to determine the to-be-compensated point, the compensation size and the compensation position of the to-be-compensated point; the to-be-compensated point is automatically compensated according to the compensation size and the compensation position, to obtain a plurality of preliminary machining points; the machining measurement is performed on the plurality of preliminary machining points, and the machining end instruction is generated according to the measurement result of each preliminary machining point. In the above manner, each machining point is automatically compensated based on the compensation measurement result of each machining point, the machining measurement is performed on the plurality of preliminary machining points obtained after the automatic compensation, the machining end instruction is generated according to the measurement result of each preliminary machining point, and the machining is ended, so that the automatic compensation and the automatic machining are realized, the manual trial cutting, judgment and human intervention are cancelled, the equipment downtime is effectively reduced, the machining production efficiency is improved, and the safety hidden danger in the machining process is reduced.

[0078] Reference Figure 3 , Figure 3 The flowchart of the machining method of the numerical control machine tool according to the second embodiment of the present application is shown.

[0079] Based on the first embodiment, in the machining method of the numerical control machine tool, the step S30 comprises the following steps.

[0080] Step S31: The machining measurement is performed on the plurality of preliminary machining points, to obtain the measurement result of each preliminary machining point.

[0081] It should be noted that after the plurality of preliminary machining points are determined, the size of each preliminary machining point is measured again, the actual measurement size of each preliminary machining point is obtained, and the actual measurement size of each preliminary machining point is the measurement result of each preliminary machining point.

[0082] Step S32: The to-be-machined program and the error machining point are determined according to the measurement result of each preliminary machining point, the basic size of each preliminary machining point and the tolerance range of each preliminary machining point.

[0083] It should be noted that whether the actual measurement size of each preliminary processing point is within the tolerance range of the basic size is determined. If the actual measurement size is within the tolerance range of the basic size, it means that the processing program corresponding to each preliminary processing point is qualified, and each preliminary processing point has met the requirements. At this time, the processing end instruction is generated to complete the processing.

[0084] It can be understood that if the actual measurement size of each preliminary processing point is not within the tolerance range of the basic size, it means that the processing program corresponding to each preliminary processing point is not processed in place during processing. The preliminary processing point whose actual measurement size is not within the tolerance range of the basic size is the error processing point, and the processing program corresponding to the error processing point is the to-be-processed program.

[0085] Step S33: Processing the error processing point according to the to-be-processed program to obtain a plurality of fine processing points.

[0086] It should be noted that the error processing point is processed according to the to-be-processed program to obtain a processed error processing point. The processed error processing point and the preliminary processing point whose actual measurement size is within the tolerance range of the basic size together constitute the fine processing point.

[0087] Step S34: Compensating measurement is performed on each fine processing point, and a processing end instruction is generated according to the measurement result of each fine processing point.

[0088] It should be noted that the compensating measurement is performed on each fine processing point to determine the actual measurement size of each fine processing point. The actual measurement size of each fine processing point is the measurement result of each fine processing point. It is determined whether the actual measurement size is within the tolerance range of the basic size. If the actual measurement size is within the tolerance range of the basic size, it is determined to generate a processing end instruction.

[0089] It can be understood that in order to ensure the processing accuracy when processing the to-be-processed material, further, the compensating measurement is performed on each fine processing point, and the processing end instruction is generated according to the measurement result of each fine processing point. It includes: compensating measurement is performed on each fine processing point according to the measurement mode of each fine processing point to obtain the measurement result of each fine processing point; determining a compensating measurement state according to the measurement mode, the measurement result of each fine processing point, the basic size of each fine processing point and the tolerance range of each fine processing point; and determining the processing end instruction according to the compensating measurement state.

[0090] In a specific implementation, the compensation measurement of each fine processing point is performed according to the measurement mode of each fine processing point, and it is determined whether the actual measurement result of each fine processing point is within the tolerance range of the basic size. If the actual measurement size is within the tolerance range of the basic size, the compensation measurement state is a non-compensation state. If the actual measurement size is not within the tolerance range of the basic size, the compensation measurement state is a to-be-compensated state. When the compensation measurement state is the non-compensation state, a processing end instruction is generated.

[0091] It should be noted that when the compensation measurement state of the fine processing point is the to-be-compensated state, the fine processing point needs to be further automatically compensated and processed. Further, the generation of the processing end instruction according to the compensation measurement state includes: when the compensation measurement state is the to-be-compensated state, determining the fine compensation size and the fine compensation position of the fine compensation point; automatically compensating the fine compensation point according to the fine compensation size and the fine compensation position to obtain a plurality of target processing points; performing processing measurement on each target processing point to determine the measurement result of each target processing point; generating the size range of each target processing point according to the basic size and the tolerance range of each target processing point; determining the detection state of each target processing point according to the measurement result and the size range of each target processing point; and determining the generation of the processing end instruction when the detection state of each target processing point is a qualified state.

[0092] It can be understood that when the compensation measurement state of the fine processing point is the to-be-compensated state, the fine processing point is the fine compensation point, and the compensation size and the compensation position of the fine compensation point are determined according to the measurement mode, the actual measurement size, the basic size, and the tolerance range of the fine processing point. The compensation size of the fine compensation point is the fine compensation size, and the compensation position of the fine compensation point is the fine compensation position.

[0093] In a specific implementation, the fine compensation point is automatically compensated according to the fine compensation size and the fine compensation position. The compensated fine compensation point and the points in all fine processing points that do not need to be compensated together constitute target processing points. The size of each target processing point is measured to obtain the actual measurement size of each target processing point, which is the measurement result. It is compared whether the measurement result of each target processing point is within the size range. If yes, the detection state is a qualified state, otherwise it is an unqualified state. When the detection state is the qualified state, a processing end instruction is generated.

[0094] It should be noted that when the detection state is an unqualified state, the unqualified machining program in the machining process needs to be identified, the target machining point corresponding to the unqualified machining program in the machining process is specified for machining, after the specified machining is completed, the target machining point after machining is measured again, and when the actual measured size of the target machining point after machining meets the tolerance range of the basic size, it is determined that the machining result instruction is generated, so that the machining is ended. As shown in Figure 4 After machining, the steps of automatic measurement + automatic compensation are performed, automatic compensation is performed after measurement, the steps of automatic start program + automatic measurement + automatic compensation are performed after compensation, the machining program to be executed is automatically identified through the measured point, the probe is adjusted to punch and measure after machining is completed, automatic compensation is performed after measurement is completed, and the machining program to be executed is automatically identified through the measured point again after compensation is completed, until it is qualified.

[0095] In the embodiment, the measurement results of the preliminary machining points are obtained by machining measurement on the preliminary machining points, the machining program to be processed and the error machining point are determined according to the measurement results of the preliminary machining points, the basic sizes of the preliminary machining points and the tolerance ranges of the preliminary machining points, the error machining point is machined according to the machining program to be processed, a plurality of fine machining points are obtained, the compensation measurement is performed on each fine machining point, and the machining end instruction is generated according to the measurement results of the fine machining points. Through the above-mentioned manner, the machining program to be processed and the error machining point are determined based on the measurement results of the preliminary machining points, the error machining point is automatically machined according to the machining program to be processed, the automatic measurement and automatic compensation process are performed after machining is completed, the machining end instruction is generated according to the measurement results of the compensation measurement, the full automation of the machining process is realized, and the machining precision is ensured.

[0096] In addition, with reference to Figure 5 , the embodiment of the present application also provides a machining device of a numerical control machine tool, which comprises:

[0097] A determination module 10 is configured to determine the point to be compensated, the compensation size and the compensation position of the point to be compensated according to the compensation measurement results and the compensation mode of each machining point.

[0099] A measurement module 30 is configured to perform machining measurement on the preliminary machining points, and determine the machining end instruction according to the measurement results of the preliminary machining points.

[0100] This embodiment determines the point to be compensated, its compensation size, and compensation position based on the compensation measurement results and compensation method of each processing point. It then automatically compensates the point to be compensated according to the compensation size and position, obtaining multiple preliminary processing points. Processing measurements are performed on these preliminary processing points, and a processing end command is generated based on the measurement results of each preliminary processing point. Through this method, automatic compensation is performed on each processing point based on the compensation measurement results. Processing measurements are then performed on the multiple preliminary processing positions obtained after automatic compensation. Finally, a processing end command is generated based on the measurement results of each preliminary processing point to terminate processing. This achieves automatic compensation and automatic processing, eliminating the need for manual trial cutting, judgment, and human intervention. This effectively reduces equipment downtime, improves processing efficiency, and reduces safety hazards during the processing.
