Workpiece program interpretation method for machine tool

The present invention relates to an interpreting method; in particular, to a workpiece program interpreting method for a machine tool, which provides a set of interpreting customized standard G or customized standard M code for a machine operator. method.

Generally, the workpiece is designed from the beginning of the prototype to the final machining. The machining process is roughly as shown in the first figure. If the prototype of the original workpiece design prototype 11 is too complicated, it must be assisted by the auxiliary software, for example, using CAD drawing. 12 draw a 3D map that conforms to the actual size of the workpiece and use the CAM design processing flow 13 to design a complete machining process based on the CAD drawing. The whole process includes the selection of the machining tool, the selection of the machining path, the distribution of the feed rate, and the like. Finally, the post-processing 14 converts these processing paths into numerically-controlled processing programs 17 that the numerical control device can recognize to produce the finished workpiece 18. If the original workpiece design prototype 11 has a simple shape or a certain regularity, in order to speed up the production rate or save the development cost, the machine operator directly writes the processing program 15 directly, and then continuously optimizes the processing program 16 to obtain the final The machining program 17 is numerically controlled to produce the finished workpiece 18 of the workpiece.

However, the use of auxiliary software such as CAD or CAM is not only a waste of cost, but also has a relatively good efficiency. In this case, the machine operator must directly write the machining program. Usually the machine operator will use the G and M codes. Or other instructions to describe the machining program, and intuitively edit the machining program with the operation of the machine operator. However, the actual machining process often produces repetitive actions, such as machining with equal-division drilling when using an indexing machine. The writing of the program is as shown in the second figure. The machine operator must intuitively judge when the indexing plate (M11) should be locked with the bolt to ensure that the position of the rotating shaft is fixed during machining, and it is necessary to intuitively judge when it should be unplugged. The bolt loosens the indexing plate (M10) for the positioning of the rotary axis, so the complicated machining instructions for loosening (M10) and locking (M11) indexing plates are programmed in the machining program, which is quite practical. inconvenient.

In view of the inconvenience of the above operation and in order to avoid the loosening of the indexing plate positioning and the locking command input, the experienced person will package the G00 and M11, M10 in the processing program into a macro or subprogram, and rewrite it into the third. The figure shows a schematic diagram of a simplified macro drilling (subprogram) programming simplification of the boring drilling program. The programming is simplified by the main program 31 plus the G100 subroutine 32, but the G100 is only a general custom G code and is not standard. The G code must additionally define G100. If the machining step is modified, it may be necessary to change the writing method. It is not effective for the machine operator to save the time required to write the machining program.

In summary, how to design a customized G or customized M code in accordance with the original standard G or standard M code instructions to improve the programming efficiency is a very important capacity of the machine operator. index.

In order to solve the above related problems, one of the main objects of the present invention is to provide a method for interpreting a workpiece program for a machine tool, which is a customized standard G designed by a machine operator according to the original standard G or standard M code. Or custom standard M code, instead of the custom G and M codes that are generally defined by the standard G or standard M code and need to be additionally defined, and with a set of methods for interpreting the customized standard G and M codes, can be effective Save time in writing a machining program and increase productivity.

If the judgment result is yes, enter the interpretation process of the standard G code or the standard M code and proceed to the next step. If the judgment result is no, the process proceeds to a process other than the standard G or the standard M code. Interpretation of a single-segment instruction; determining whether the currently-processed single-segment instruction belongs to a hierarchy or a sub-program, and this step further includes: determining a processing block when processing a single-segment instruction to be a main program Whether the standard G code or the standard M code contained in the instruction is registered as a customized standard G code or a customized standard M code. If the judgment result is yes, the call is further loaded and loaded to represent the customized standard G. Standard or custom one of M code subroutine, and then starts the read line by line in a plurality of rows subroutine processing of single instruction And interpreting, if the judgment result is no, the general standard G code or M code is interpreted; and when the level of the processing single block instruction is a subprogram, it is first determined whether the subprogram is already a customized standard G The code or the customized standard M code, if the judgment result is yes, the standard G code or the standard M code contained in the currently processed processing block instruction is interpreted by the general standard G code or M code, if the judgment result is If not, it is judged whether the standard G code or the standard M code contained in the processing single block instruction is registered as a customized standard G code or a customized standard M code. If the judgment result is yes, then further call and Loading one of the sub-programs representing the customized standard G code or the customized standard M code, and then starting to read the plurality of lines in the sub-program to process the block instruction and interpreting, if the judgment result is no, proceed Interpretation of the general standard G code or M code; and determining whether the processing block instruction is a program end instruction, and when the machining block instruction is a program end instruction, the instruction end system is determined according to the hierarchy to which the machining block instruction belongs.

The present invention mainly discloses a workpiece program interpretation method for a machine tool, and provides a set of interpreters for the customized standard G and M codes designed by the machine operator according to the original standard G and M codes. The method of standardizing G and M codes. The basic principles and functions of the workpiece program of the machine tool related to the present invention are well known to those skilled in the relevant art, and therefore, the following description is directed only to the method for interpreting the machine tool with the present invention. The features are described in detail. In addition, the drawings in the following texts are not completely drawn in accordance with actual relevant dimensions, and their function is only to show a schematic diagram relating to the features of the present invention.

First, please refer to FIG. 4, which is a flow chart of the method for interpreting the workpiece program for the machine tool according to the present invention, and is customized for the machine operator according to the original standard G or the standard M code. Standard G or custom standard M code, a set of procedures for interpreting customized G and M codes. As shown in FIG. 4, in the embodiment, the flow of the workpiece program interpretation method for the machine tool includes the following steps:

Step 40: Load the workpiece program to be executed by the user; the workpiece program has a plurality of processing unit instructions, and a workpiece program is loaded for the machine tool to perform the machining operation, and then proceeds to step 41.

Step 41: The program to be executed is read line by line to start the interpretation, and the level of the currently read program of the line belongs to the main program or the sub program, and then proceeds to step 42.

Step 42: Read the processing block instruction of the single line workpiece program; this step mainly reads one of the processing block instructions of the plurality of row processing block instructions in the workpiece program, and then proceeds to step 43.

Step 43: Determine whether the currently processed processing block instruction already includes a standard G code or a standard M code. If the determination result is yes, proceed to step 44 to enter the interpretation process of the standard G code or the standard M code, if it is determined If the result is no, the process proceeds to step 45 to interpret the processing block instructions other than the standard G or standard M code.

Step 44: Enter the interpretation process of the standard G code or the standard M code; this process is mainly for the interpretation process provided by the customized standard G or standard M code as shown in FIG. 5.

Step 45: Perform interpretation of a processing block instruction other than the standard G or standard M code; the processing block instruction includes other processing single block instructions or non-standard G code, M in addition to the standard G code or the standard M code. The general custom G and M codes of the code, after the completion of this step, the representative is finished. In the interpretation of the line, the next line of the workpiece program will continue to be interpreted.

Step 46: When the processing of the processing block instruction is the program end instruction, the program end instruction is judged to be the end of the main program or the end of the sub program according to the level to which the processing unit block instruction belongs, and if the line workpiece program is judged If the sub-program is a sub-program, that is, the end program of the program represents the end of the sub-program, then you need to skip to step 47 and return to the previous level to continue the interpretation. If you judge that the program of the line belongs to the main program, On behalf of the end of program, the command represents the end of the main program, then jump to the last step 48 to determine the completion of the interpretation.

Step 47: Return to the previous level; the upper level referred to in this step refers to the level of returning to the main program. When the processing unit of the line belongs to the level of the subprogram, the subprogram indicates that the main program has not been interpreted yet, and must jump back. Go to the previous level to continue the interpretation of the main program.

Step 48: The explanation is completed, that is, the end of the main program, and the interpretation of the entire workpiece program to be processed is completed.

Please refer to FIG. 5, which is a flowchart of interpretation of the standard G code or standard M code of the present invention, which is an interpretation process provided by the customized standard G and M codes. In the above process, step 44 Entering the standard G code or standard M code interpretation process, further includes the following steps:

Step 440: judging that the level of the processing single block instruction currently read belongs to the main program or the subprogram. When the processing of the processing unit of the line belongs to the main program, the process jumps to step 441 to continue. When the level to which the line processing block instruction belongs is a subprogram, the process jumps to step 442 to continue.

Step 441: When the level of the processing of the single-segment instruction belongs to the main program, proceed directly to step 443 to determine whether the standard G code or the standard M code included in the processing unit of the line is registered as a customized standard G code. Or a custom standard M code.

Step 442: When the level to which the processing block instruction belongs belongs to the subprogram, proceed to step 446 to continue to determine whether the subprogram is already a customized standard G code or a customized standard M code.

Step 443: Determine whether the standard G code or the standard M code included in the processing block instruction is registered as a customized standard G code or a customized standard M code. If the determination result is yes, proceed to step 445 to further call and carry Enter a subroutine representing the customized standard G code or the customized standard M code. If the judgment result is no, then go to step 444 to perform the interpretation of the general standard G code or the standard M code; Customized standard G code or custom standard M code subroutine It can be regarded as a workpiece program, so the subroutine needs to be further interpreted. The interpretation method must be interpreted line by line like the main program.

Step 444: Interpretation of the general standard G code or the standard M code; after the completion of the step, the standard G code or the standard M code is interpreted, and then skip to step 45 to continue the processing other than the standard G or standard M code. Interpretation of single-segment instructions.

Step 445: loading a subroutine of a customized standard G code or a customized standard M code; the subroutine of the customized standard G code or the customized standard M code may also be a macro that uses a logical grammar Set program.

Step 446: Determine whether the subroutine is a customized standard G code or a customized standard M code. If the judgment result is yes, proceed to step 444 to process the standard G code included in the processing unit of the currently read line. Or the standard M code is used to interpret the general standard G code or M code. If the judgment result is no, then the process jumps to step 443 to continue the subsequent judgment.

According to the above description, the method for interpreting the machine tool provided by the present invention can provide a set of customized standard G and M codes designed by the machine operator according to the original standard G and M codes. Interpreting the method of customizing standard G and M codes, this method can achieve the processing requirements of various machines, and it is easier to write the processing program, which can improve the processing efficiency.

Taking the application of the indexing disk as an example, please refer to FIG. 6, which is a schematic diagram of the main program and macro of the customized standard G code or the customized standard M code of the present invention. As shown in Fig. 6, first, the standard G codes G00 and G01 are registered as the customized standard G code, and two macros G00 and G01 are added, wherein the macro writing method is as shown in Fig. 6 and 61, 62. Further assume that the current control axis has X, Y, Z, C, where C represents the rotation axis, and C is used as the judgment command in the macro set, indicating that the two macros G00 and G01 are the customized standard G of the rotation axis positioning command. The code automatically determines whether to perform the rotation axis positioning. If there is a command to judge C, the M11 is pressed to lock the indexing plate. If there is no instruction to judge C, the M10 is pressed to release the indexing plate. Customized by the standard G code G00 and G01, the indexing plate is automatically released when the rotary axis is positioned, and the indexing plate is automatically locked after the positioning is completed, so that the machine operator does not need to write the machining program. The complicated processing of the loosening (M10) and locking (M11) indexing discs allows the machining program to simplify the writing of the main program as shown in Fig. 6, as long as the customized standard G code is read into the main program. G00 and G01 can be used to determine the release and locking action of the indexing plate with the positioning angle of the rotary axis C. This saves the time required to write the machining program and greatly improves the production efficiency.

The invention can be applied not only to the indexing disc but also to many types of processing machines, such as an electric discharge machine and a woodworking cutting machine. First, in the case of an electric discharge machine, in the actual processing, the machining debris is accumulated due to discharge. Therefore, it is necessary to continue to advance for a certain distance and then retreat for cleaning operations, but this action is regular. As long as the well-designed customized standard G code macro is used, the processing program can be simplified. In addition, the woodworking cutting machine In general, the cutter of the general cutting machine is a giant piece, which can only be cut along the tangential direction with G01 (straight line cutting), G02 (clockwise circular cutting), G03 (counterclockwise circular cutting), so when cutting The direction of the tool must match the rotation, but the tool cannot be rotated in an instant. It must be rotated before the knife is removed, so if you can design the G01, G02, G03 macro with the customized standard G code, use the rotation command. It will also be convenient.

In summary, according to the foregoing design description, the present invention is directed to the customized standard G and M codes designed by the machine operator according to the original standard G and M codes, instead of the general use of the standard G and M codes. The additional custom G and M codes are required, and a set of methods for interpreting the customized G and M codes can save the time required to write the machining program, which not only increases the convenience of operation, but also increases the convenience of operation. Improve processing efficiency, thereby improving processing efficiency and achieving better system stability.
