Background Art

[0002] The finishing of the main shaft hole, camshaft hole, idler shaft hole and other hole systems is a key process of the engine. In order to ensure the coaxiality and processing efficiency of each hole, it should generally be completed in one time by a boring bar. However, because the boring bar is generally slender, it is necessary to add a guide sleeve support to the crotch part such as the main shaft hole, which makes it impossible for the boring bar to complete the processing in one feed.

However, for the programming of features such as engine spindle holes and camshaft holes, since operations such as tool release and spindle orientation are required, conventional programming methods cannot achieve such complex actions.

[0035] In this embodiment, a post-processing method for a tool location source file of boring programming running on a mobile terminal, a computer terminal or a similar computing device is provided.

[0036] Figure 21 is a flowchart of a post-processing method of a tool location source file for boring programming according to an embodiment of the present application. The tool location source file is a program file for boring a plurality of coaxial holes of a workpiece to be processed using a CNC machine tool, and the CNC machine tool may be a machining center. Figure 2 As shown, the method comprises the following steps:

[0037] Step S201, according to a preset tool letting distance, a preset spindle orientation angle and a first moving position in the tool position source file, determine the coordinates of the tool letting position in the first direction and the coordinates in the second direction, and according to the second moving position in the tool position source file and a first preset tool compensation, determine the coordinates of the tool letting position in the third direction, obtain the tool letting position, and write a tool letting program for controlling the tool of the CNC machine tool to move to the tool letting position into a CNC program template, the spindle orientation angle is a fixed orientation angle of the spindle of the CNC machine tool, the first moving position is a position indicated by the first moving instruction, the second moving position is a position indicated by the second to last cycle processing instruction, the first preset tool compensation is a tool compensation value of the first fine boring tool point of the CNC machine tool in the third direction, the first direction, the second direction and the third direction are perpendicular to each other, and the third direction is parallel to the center axes of the plurality of coaxial holes;

[0038] Specifically, the multiple coaxial holes in the workpiece to be processed are arranged at intervals, and the central axes of the multiple coaxial holes coincide and are parallel to the third direction. The tool includes multiple boring tool structures, and the boring tool structures correspond to the coaxial holes one by one. The spindle of the CNC machine tool drives the tool to move, and controls the multiple boring tool structures to process the corresponding multiple coaxial holes at the same time. In the process of the boring tool structure moving to the boring surface of the corresponding coaxial hole, it is necessary to avoid the blank surface of the coaxial hole that it does not process and the supporting guide sleeve on the boring die mechanism to avoid interference with the blanks and guide sleeves of these unprocessed coaxial holes. The tool clearance distance is the distance that the boring tool structure needs to avoid, and the tool clearance position is the position where each boring tool structure does not interfere with the blank surface and guide sleeve of any coaxial hole. The boring surface is the surface of the coaxial hole to be bored. When the tool is located at the tool-releasing position, in the third direction, the coaxial holes and the boring tool structure are arranged in the order of the last coaxial hole, the last boring tool structure, the penultimate coaxial hole, the penultimate boring tool structure, ..., the first coaxial hole, the first boring tool structure. The penultimate cycle processing instruction is an instruction for processing the penultimate coaxial hole using the penultimate boring tool structure. The first fine boring blade is a fine boring blade in the boring tool structure (i.e., the first boring tool structure) that performs a boring operation on the first coaxial hole. A boring bar is mounted on the spindle.

[0039] Step S202, determining a return position after tool letting go according to the first moving position and the second moving position, and writing a return program for controlling the tool to move to the return position after tool letting go after the tool letting go program in the numerical control program template;

[0040] Specifically, the tool return position is the position where each boring tool structure of the tool moves to the corresponding center axis of the coaxial hole after the tool is released. The tool return position can be the same as the coordinates of the machining (boring) start position in the first direction and the second direction.

[0041] Step S203, determining the processing parameters according to the tool position source file, and writing the processing program that controls the tool to run according to the processing parameters into the return program in the CNC program template, thereby obtaining a CNC program file that controls the CNC machine tool processing, and the CNC program file is used to simultaneously perform the boring operation on multiple coaxial holes.

[0042] Specifically, the processing parameters are control parameters for boring the coaxial hole, and the processing parameters may include processing (boring) process parameters such as the processing (boring) start position, the processing (boring) end position, and the feed rate. The NC program template is a template file of the NC program for controlling the NC machine tool processing, and the NC program file is also called an NC program file.

[0043] Through the embodiment, firstly, according to the tool letting distance, the spindle orientation angle and the first moving position in the tool position source file, the coordinates of the tool letting position in the first direction and the second direction are determined, and according to the second moving position in the tool position source file and the first preset tool compensation, the coordinates of the tool letting position in the third direction are determined, thereby obtaining the tool letting position and writing the tool letting program for controlling the tool to move to the tool letting position into the NC program template; then, according to the first moving position and the second moving position, the return position after tool letting is determined and the return program for controlling the tool to move to the return position after tool letting is written after the tool letting program; finally, according to the tool position source file, the machining processing parameters are determined, and after the machining processing program for controlling the tool to run according to the machining processing parameters is written into the return program, a NC program file for simultaneously performing boring operations on multiple coaxial holes of the workpiece to be machined is obtained. In the process of post-processing the tool position source file, the present application determines the tool position, the return position after tool release, and the processing parameters according to the tool release distance, the spindle orientation angle, and the information in the tool position source file, and generates a tool release program, a return program after tool release, and a processing program correspondingly and writes them into the NC program template to obtain a NC program file. Through the NC program file, the NC machine tool can be automatically controlled to perform boring operations on multiple coaxial holes of the workpiece to be processed at the same time, and the effect of automatically adding the tool release program in the process of translating the tool position source file into a program directly available to the NC machine tool is achieved. There is no need to manually add the tool release program in the NC program after obtaining it, which liberates manpower and solves the problem that conventional programming methods cannot realize complex tool release actions and need to manually modify the program, resulting in a waste of human resources. In addition, compared with the prior art, the solution of the present application improves the efficiency of generating NC program files directly available to the NC machine tool.

[0044] It should be noted that the workpiece to be processed with multiple coaxial holes is located on a boring die mechanism with a supporting guide sleeve, and the boring die mechanism is located at a limited position on the rotary platform of the CNC machine tool, and the limited position is used to define the coaxial holes in a one-to-one correspondence. Multiple boring tool structures are spaced on the boring bar, and the distance between the first limited position and the second limited position and the distance between the first boring tool structure and the second boring tool structure are the same, and so on, so that the limited positions correspond to the boring tool structures on the boring bar in a one-to-one correspondence. In addition, it should be noted that in the program for controlling the tool to move to various positions, the spindle is controlled to move from the origin to these positions, thereby driving the tool to move to the corresponding position, which is equivalent to controlling the last boring tool structure to move to these positions. Since the positions between the multiple boring tool structures are fixed and correspond to the positions of the multiple coaxial holes of the workpiece to be processed, each boring tool structure can be driven to the corresponding position through the movement.

[0045] Moreover, each of the boring tool structures includes a fine boring blade and a rough boring blade, and the rough boring blade is in front. The plurality of coaxial holes may include a main shaft hole, a cam shaft hole, and an idler shaft hole.

[0046] In an optional solution, the first moving position includes a first moving coordinate value X0 in the first direction, a second moving coordinate value Y0 in the second direction, and a third moving coordinate value Z0 in the third direction, which are recorded as position (X0, Y0, Z0); the second moving position includes a fourth moving coordinate value X2 in the first direction, a fifth moving coordinate value Y2 in the second direction, and a sixth moving coordinate value Z2 in the third direction, which are recorded as (X2, Y2, Z2); according to a preset tool clearance distance L, a preset spindle orientation angle SDIR, and the first moving position in the tool position source file, the coordinates of the tool clearance position in the first direction and the coordinates of the second direction are determined; and according to the second moving position in the tool position source file and the first preset tool compensation, the coordinates of the tool clearance position in the third direction are determined, including: according to the tool clearance distance, the spindle orientation angle SDIR, and the first moving position in the tool position source file, the coordinates of the tool clearance position in the third direction are determined. According to the spindle orientation angle and the first moving coordinate value, a first compensation value is determined to be the product of the cosine value of the spindle orientation angle and the tool letting distance, and a coordinate X1 of the tool letting position in the first direction is determined to be the sum of the first compensation value and the first moving coordinate value, that is, X1=X0+L*cos(SDIR); according to the tool letting distance, the spindle orientation angle and the second moving coordinate value, a second compensation value is determined to be the product of the sine value of the spindle orientation angle and the tool letting distance, and a coordinate of the tool letting position in the second direction is determined to be the sum of the second compensation value and the second moving coordinate value, that is, Y1=Y0+L*sin(SDIR); according to the sixth moving coordinate value and the first preset tool compensation D3, a coordinate of the tool letting position in the third direction is determined to be the sum of the sixth moving coordinate value and the first preset tool compensation, that is, Z2+D3. In the embodiment, the tool letting distance is converted into the tool letting amount in the first direction and the tool letting amount in the second direction according to the spindle orientation angle, and the tool letting amount is added to the first moving position to obtain the coordinates of the tool letting position in the first direction and the coordinates in the second direction, and in consideration of problems such as tool wear and deviation, the first preset tool compensation is added to the coordinates of the second moving position in the third direction to obtain the coordinates of the tool letting position in the third direction, so that a more accurate tool letting position can be obtained, which facilitates the subsequent acquisition of a CNC program file that can more accurately control the CNC machine tool to perform the tool letting action.

[0047] The sixth moving coordinate value is the sum of the boring end position of the penultimate coaxial hole and the bottom offset. Each of the coaxial holes includes two opposite boring surfaces, which are the top boring surface and the bottom boring surface in the order of boring. The boring end position is the coordinate of the boring surface of the penultimate coaxial hole close to the last coaxial hole (i.e., the bottom boring surface of the penultimate coaxial hole) in the third direction. The bottom offset is a preset offset value.

[0048] Specifically, after determining the coordinates of the tool-release position in the first direction and the coordinates in the second direction, the method further includes: writing a spindle orientation program for controlling the spindle to be oriented to the spindle orientation angle into the numerical control program template, and the program is located before the tool-release program, that is, the spindle orientation rotation is performed before the tool-release; updating the first moving position to include the coordinates of the tool-release position in the first direction, the coordinates of the tool-release position in the second direction, and the position of the third moving coordinate value, that is, the updated first moving position is (X1, Y1, Z0), and writing an initial moving program for controlling the tool to move to the updated first moving position into the numerical control program template, and the program is located between the spindle orientation program and the tool-release program. In this embodiment, the program for controlling the spindle to rotate is first written into the numerical control program template according to the spindle orientation angle, so as to realize the writing of the spindle position initialization program before the tool moves, and then the first moving position in the tool position source file is updated according to the tool-release distance, and the program for controlling the tool to move to the updated first moving position is written into the spindle orientation program, so as to further avoid the problem of interference and collision between the boring tool structure and the coaxial hole during the first tool movement process.

[0049] Specifically, the updated first moving position is also called the tool letting start position. The tool letting position is also called the tool letting end position. In an exemplary embodiment, when the tool is located at the tool letting start position, in the third direction, the coaxial holes and the boring tool structure are arranged in the order of the last coaxial hole, the second to last coaxial hole, ..., the first coaxial hole, the last boring tool structure, the second to last boring tool structure, ..., the first boring tool structure.

[0050] Further, according to the first moving position and the second moving position, the return position after the tool is released is determined, including: determining the return position after the tool is released as a position including the first moving coordinate value, the second moving coordinate value and the sixth moving coordinate value, that is, the return position after the tool is released is (X0, Y0, Z2). By controlling the program of the tool from the tool release position to the return position after the tool is released, each boring tool structure is moved in the third direction to the front of the top boring surface of the corresponding coaxial hole, and the boring tool structure overlaps with the projection of the corresponding coaxial hole on the plane formed by the first direction and the second direction, so as to facilitate the execution of the subsequent processing program.

[0051] In other embodiments of the present application, before determining the coordinates of the tool letting position in the first direction and the coordinates in the second direction according to a preset tool letting distance, a preset spindle orientation angle and the first moving position in the tool position source file, the method further includes: upon receiving a start operation for post-processing of the tool position source file, displaying an editing interface on a display panel, the editing interface including an edit box for a tool grabbing position, an edit box for a grasping angle of the spindle, an edit box for a tool grasping direction vector, an edit box for the tool letting distance and an edit box for the spindle orientation angle; determining the tool grabbing position, the grasping angle of the spindle, the tool grasping direction vector, the tool letting distance and the spindle orientation angle in response to a predetermined operation acting on the editing interface; and before writing an initialization program for controlling the CNC machine tool to execute in-machine tool grabbing into the tool letting program in the CNC program template according to data information between a starting program and the first moving instruction in the tool position source file, the tool grabbing position, the grasping angle of the spindle and the tool grasping direction vector. The specific values ​​of the tool gripping position, the spindle gripping angle, the tool gripping direction vector, the tool clearance distance and the spindle orientation angle are set through human-computer interaction, and then a program for initializing the CNC machine tool is generated from these values ​​and written into a CNC program template. Through this initialization program, the absolute coordinate system can be made to correspond to the machine coordinate system of the CNC machine tool established by the user.

[0052] In the actual application process, the tool position source file is located in the CAM programming software, which can be specifically NXCAM, MasterCAM, CIMATRON, PowerMILL and other programming software. By clicking the post-processing operation button in the CAM programming software, the post-processing start operation of the tool position source file is generated. The display panel is the display panel of the electronic device where the CAM programming software is located. The tool position source file is specifically a file generated by the CAM software that contains tool coordinate data and needs to be post-processed, generally in the APT language format. The post-processing described in this application is the process of converting the machining tool position source file generated by the CAM software into an NC program that can be read by a specific machine tool.

[0053] A person skilled in the art can set the tool gripping position, the spindle gripping angle, the tool gripping direction vector, the tool gripping distance, and the spindle orientation angle by operating the edit box of the tool gripping position, the edit box of the spindle gripping angle, the edit box of the tool gripping direction vector, the edit box of the tool clearance distance, and the edit box of the spindle orientation angle. The edit box can be an input box or a selection box displayed on the display panel.

By writing the program, the NC program file has the control function of controlling the rotary table to rotate to drive the tool to rotate, then grasping and retracting the tool according to the position after rotation, and finally controlling the rotary table to rotate back to the original position (i.e., the position before rotating the rotation angle). By controlling the tool to retract to the first safe position, the problem of interference with the tool during the process of the rotary table rotating back to the original position is avoided.

[0056] Further, according to the direction vector and the tool grabbing direction vector, the specific process of determining the rotation angle of the turntable is: BPOS=acos((TVEC*ZVEC) / (|TVEC|*|ZVEC|)), BPOS is the rotation angle, TVEC is the tool grabbing direction vector, and ZVEC is the direction vector. According to the tool grabbing position, the rotation angle and the rotation center position, the tool grabbing position is updated, and the specific process of obtaining the updated tool grabbing position is:

[0057] The coordinates of the updated gripper position in the first direction are determined as:

[0058] XPOS=cos(atan2(XORI-XROT,ZORI-ZROT)+BPOS*PI / 180)*sqrt((XORI-XROT)^2+(ZORI-ZROT)^2)+XROT;

[0059] Determine the coordinates of the updated gripper position in the second direction as YPOS=YORI;

[0064] Specifically, the last cycle processing instruction is an instruction to use the last boring tool structure to process the last workpiece to be processed. The first rough boring blade is a rough boring blade in the boring tool structure (ie, the first boring tool structure) that performs a boring operation on the first workpiece to be processed.

By generating the processing program, the second tool retraction program and the tool placement program, the NC machine tool can realize the automatic processing, tool retraction and tool placement processes of the workpiece to be processed when executing the NC program file.

[0066] The first safety position and the second safety position may be the same or different.

[0067] Specifically, before generating a second tool retraction program for controlling the tool to retract to a second safety position, the method further includes: determining the second safety position according to the tool letting position, the first moving position and a third preset tool compensation, wherein the coordinate of the second safety position in the first direction is the coordinate X1 of the tool letting position in the first direction, the coordinate of the second safety position in the second direction is the coordinate Y1 of the tool letting position in the second direction, the coordinate of the second safety position in the third direction is the sum of the third moving coordinate value Z0 and a third preset tool compensation, the third preset tool compensation is the tool compensation value of the front end of the boring bar of the CNC machine tool in the third direction, and the front end of the boring bar is the end point of the boring bar located on the side of the first rough boring blade away from the first fine boring blade.

[0083] YPOS=YORI;

[0084] ZPOS=sin(atan2(XORI-XROT,ZORI-ZROT)+BPOS*PI / 180)*sqrt((XORI-XROT)^2+(ZORI-ZROT)^2)+ZROT;

[0086] Step S3: Processing knife data:

[0087] Step S31: adding a spindle orientation program segment "SPOS=SDIR" at the initial moving position to control the spindle orientation to the spindle orientation angle;

[0088] Step S32: Calculate the starting position of the knife:

[0089] Read the coordinate data after the first occurrence of the rapid movement instruction "RAPID" in the tool source file, and record the X, Y, and Z coordinate values ​​as X0, Y0, and Z0; update the initial movement coordinates of the NC program according to the eccentric distance L:

[0090] X1=X0+L*cos(SDIR);

[0091] Y1=Y0+L*sin(SDIR);

[0092] Z1=Z0;

[0093] Step S33: Calculate the knife end position:

[0094] (1) Read data to "CYCLE / OFF", record the number of CYCLEs that appear before "CYCLE / OFF", and obtain the coordinates of the "GOTO" instruction after the second-to-last "CYCLE" instruction, and mark the Z coordinate as Z2, such as Figure 5As shown, the value of Z2 is: the end position of the second to last hole surface of the hole system + bottom offset;

[0095] (2) Shield the program segment output by the CYCLE cycle and add the program segment "G0 G90 X1 Y1 Z2 D3". D3 is the radial tool compensation of the first fine boring edge contact point of the boring bar, that is, the first preset tool compensation.

[0096] (3) Add the tool return program segment "G0 G90 X0 Y0 Z2";

[0097] Step S4: Processing:

[0098] Step S41: Calculation of processing start position:

[0099] (1) Get the coordinates of the "GOTO" instruction after the last "CYCLE" instruction before "CYCLE / OFF", and mark the Z coordinate as Z3, such as Figure 5 As shown, the value of Z3 is: the starting position of the last hole surface of the hole system + top offset;

[0100] (2) Add the program segment "G0 G90 X0 Y0 Z3 D2", where D2 is the radial tool compensation of the first rough boring edge contact point of the boring bar, i.e., the second preset tool compensation;

[0101] (3) Output program segment, which includes spindle speed, feed, and spindle forward rotation instructions;

[0102] Step S42: Calculation of processing end position:

[0103] Get the boring depth value of the last "CYCLE" instruction, recorded as Z4; add the program segment "G1 G90 X0 Y0 Z4D2";

[0104] Step S5: Tool retraction processing:

[0108] The CNC machine tool runs the CNC program file obtained through the above steps, and the steps of processing the workpiece to be processed are as follows: Figure 6 As shown, the specific steps are as follows: the boring bar allows the tool to enter multiple coaxial holes and reaches the starting position of the tool letting go; the boring bar quickly feeds to the end position of the tool letting go; the tool letting go ends and the tool returns to the center; the boring bar and the guide sleeve support cooperate to feed the tool to the starting position of processing; the boring bar is driven to process the workpiece to be processed and reaches the end position of processing; the spindle is oriented to a fixed angle (at the joint surface of the tile cover); the spindle is oriented and retreated to the starting position of processing; the spindle is oriented to the spindle orientation angle; the boring bar retreats to the starting position of the tool letting go; the boring bar allows the tool to retreat.

[0109] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0110] The embodiment of the present application also provides a post-processing device for a tool location source file of boring programming. It should be noted that the post-processing device for a tool location source file of boring programming of the embodiment of the present application can be used to execute the post-processing method for a tool location source file of boring programming provided in the embodiment of the present application. The device is used to implement the embodiments and preferred implementations, and the descriptions that have been made will not be repeated. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation in hardware, or a combination of software and hardware, is also possible and conceivable.

[0111] The following introduces the post-processing device of the tool position source file for boring programming provided in the embodiment of the present application.

[0112] Figure 7 Schematic diagram of a post-processing device for a tool location source file of boring programming according to an embodiment of the present application. The tool location source file is a program file for boring a plurality of coaxial holes of a workpiece to be processed using a CNC machine tool, and the CNC machine tool may be a machining center. Figure 7 As shown, the device comprises:

[0113] A first determining unit 10 is used to determine the coordinates of the tool-releasing position in the first direction and the coordinates in the second direction according to a preset tool-releasing distance, a preset spindle orientation angle, and a first moving position in the tool position source file, and to determine the coordinates of the tool-releasing position in the third direction according to the second moving position in the tool position source file and a first preset tool compensation, to obtain the tool-releasing position, and to write a tool-releasing program for controlling the tool of the CNC machine tool to move to the tool-releasing position into a CNC program template, wherein the spindle orientation angle is a fixed orientation angle of the spindle of the CNC machine tool, the first moving position is a position indicated by the first moving instruction, the second moving position is a position indicated by the second to last cycle processing instruction, the first preset tool compensation is a tool compensation value of a first fine boring tool point of the CNC machine tool in the third direction, the first direction, the second direction, and the third direction are perpendicular to each other, and the third direction is parallel to the center axes of the plurality of coaxial holes;

[0114] Specifically, the multiple coaxial holes in the workpiece to be processed are arranged at intervals, and the central axes of the multiple coaxial holes coincide and are parallel to the third direction. The tool includes multiple boring tool structures, and the boring tool structures correspond to the coaxial holes one by one. The spindle of the CNC machine tool drives the tool to move, and controls the multiple boring tool structures to process the corresponding multiple coaxial holes at the same time. In the process of the boring tool structure moving to the boring surface of the corresponding coaxial hole, it is necessary to avoid the blank surface of the coaxial hole that it does not process and the supporting guide sleeve on the boring die mechanism to avoid interference with the blanks and guide sleeves of these unprocessed coaxial holes. The tool clearance distance is the distance that the boring tool structure needs to avoid, and the tool clearance position is the position where each boring tool structure does not interfere with the blank surface and guide sleeve of any coaxial hole. The boring surface is the surface of the coaxial hole to be bored. When the tool is located at the tool-releasing position, in the third direction, the coaxial holes and the boring tool structure are arranged in the order of the last coaxial hole, the last boring tool structure, the penultimate coaxial hole, the penultimate boring tool structure, ..., the first coaxial hole, the first boring tool structure. The penultimate cycle processing instruction is an instruction for processing the penultimate coaxial hole using the penultimate boring tool structure. The first fine boring blade is a fine boring blade in the boring tool structure (i.e., the first boring tool structure) that performs a boring operation on the first coaxial hole. A boring bar is mounted on the spindle.

[0115] A second determining unit 20 is used to determine a return position after tool letting go according to the first moving position and the second moving position, and write a return program for controlling the tool to move to the return position after tool letting go after the tool letting go program in the numerical control program template;

[0116] Specifically, the tool return position is the position where each boring tool structure of the tool moves to the corresponding center axis of the coaxial hole after the tool is released. The tool return position can be the same as the coordinates of the machining (boring) start position in the first direction and the second direction.

[0117] The third determination unit 30 is used to determine the processing parameters according to the tool position source file, and write the processing program that controls the tool to run according to the processing parameters into the return program in the CNC program template, so as to obtain the CNC program file that controls the CNC machine tool processing. The CNC program file is used to simultaneously perform the boring operation on multiple coaxial holes.

[0118] Specifically, the processing parameters are control parameters for boring the coaxial hole, and the processing parameters may include processing (boring) process parameters such as the processing (boring) start position, the processing (boring) end position, and the feed rate. The NC program template is a template file of the NC program for controlling the NC machine tool processing, and the NC program file is also called an NC program file.

[0119] Through the embodiment, the first determining unit determines the coordinates of the tool letting position in the first direction and the second direction according to the tool letting distance, the spindle orientation angle and the first moving position in the tool position source file, and determines the coordinates of the tool letting position in the third direction according to the second moving position in the tool position source file and the first preset tool compensation, thereby obtaining the tool letting position and writing the tool letting program for controlling the tool to move to the tool letting position into the NC program template; the second determining unit determines the return position after tool letting according to the first moving position and the second moving position, and writes the return program for controlling the tool to move to the return position after tool letting into the tool letting program; the third determining unit determines the machining parameters according to the tool position source file, and writes the machining program for controlling the tool to run according to the machining parameters into the return program, thereby obtaining a NC program file for simultaneously performing boring operations on multiple coaxial holes of a workpiece to be machined. In the process of post-processing the tool position source file, the present application determines the tool position, the return position after tool release, and the processing parameters according to the tool release distance, the spindle orientation angle, and the information in the tool position source file, and generates a tool release program, a return program after tool release, and a processing program correspondingly and writes them into the NC program template to obtain a NC program file. Through the NC program file, the NC machine tool can be automatically controlled to perform boring operations on multiple coaxial holes of the workpiece to be processed at the same time, and the effect of automatically adding the tool release program in the process of translating the tool position source file into a program directly available to the NC machine tool is achieved. There is no need to manually add the tool release program in the NC program after obtaining it, which liberates manpower and solves the problem that conventional programming methods cannot realize complex tool release actions and need to manually modify the program, resulting in a waste of human resources. In addition, compared with the prior art, the solution of the present application improves the efficiency of generating NC program files directly available to the NC machine tool.

[0120] The post-processing device of the tool position source file of boring programming includes a processor and a memory, the first determination unit, the second determination unit and the third determination unit are all stored in the memory as program units, and the processor executes the program units stored in the memory to realize the corresponding functions. The modules are all located in the same processor; or the modules are located in different processors in any combination.

[0121] The processor includes a kernel, which retrieves the corresponding program unit from the memory. One or more kernels can be set, and the kernel parameters can be adjusted to solve the problem that the tool position source file needs to be manually modified after being translated into the NC program before it can be used for actual processing, which takes up a lot of human resources.

[0122] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
