Fig. 1 shows schematically a flow chart of a workpiece machining program visualization method according to an embodiment of the present invention. In this embodiment, the workpiece machining program visualization method mainly comprises four steps, SI - S4. In step SI, machining information is acquired, wherein the machining information mainly comprises a workpiece machining program and a workpiece initial parameter; in step S2, the workpiece machining program is compiled in real time, to generate intermediate code; in step S3, the intermediate code is used to generate a movement path of a machining member; in step S4, the workpiece initial parameter and the movement path of the machining member are used to generate at least one intermediate result for reproducing the workpiece machining program, and the at least one intermediate result is displayed in a first display region 100. The present invention solves the problem of a workpiece machining program being unable to display in real time an intermediate form of a workpiece during machining, so that an operator can perform an inspection before actually running a workpiece machining program, reducing the error rate during actual machining, and increasing the efficiency of workpiece machining .
In step Si, the workpiece machining program may be acquired in various ways. For example, when it is necessary to input a workpiece machining program, batch import or progressive addition of the workpiece machining program may be performed by means of a system, and the workpiece machining program edited and added by the user may be stored in a memory of a machining tool. Generally, the workpiece machining program comprises at least one workpiece machining instruction, and the workpiece machining program may be recorded in the form of base code for example; the workpiece initial parameter may be for example a three-dimensional structure of a workpiece blank. In steps S2 and S3, the workpiece machining program is compiled in real time, to generate intermediate code, then a movement path of a machining member is generated on the basis of the intermediate code. In an actual machine tool machining process, relative movement occurs between a machining member and a workpiece to be machined in order to accomplish machining (e.g. actions such as cutting or paring) of the workpiece; the machining member may for example be a cutter of the machine tool. The present invention is not only suitable for a machine tool machining system, but may also be expanded to applications in other machining systems having similar assembly processes. In step S4, the workpiece initial parameter and the movement path of the machining member are used to generate at least one intermediate result for reproducing the workpiece machining program; in other words, an execution result of the workpiece machining program is simulated in advance, and the real-time execution result of the workpiece machining program is displayed visually; finally, the intermediate result of execution is displayed in the first display region 100.
The present invention also provides a workpiece machining program visualization apparatus; fig. 2 is a schematic diagram of a workpiece machining program visualization apparatus according to an embodiment of the present invention, comprising: an acquisition component 10, a compiling component 20, an execution component 30 and a display component 40. The acquisition component 10 is configured to acquire machining information, e . g . the acquisition component 10 may provide a user interface for receiving machining information inputted by a user, the machining information mainly comprising: a workpiece machining program and a workpiece initial parameter. The compiling component 20 is configured to compile the workpiece machining program in real time, and generate intermediate code ; in one preferred embodiment , the compiling component 20 may also inspect errors in the workpiece machining program, e.g. lexical errors, syntax errors, semantic errors and debugging errors in program code, the occurrence of interference in a movement path of a machining member, and interpolation errors, etc. The execution component 30 is configured to use the intermediate code to generate a movement path of a machining member; in other words, the execution component 30 receives the intermediate code from the compiling component 20, computes the movement path of the machining member on the basis of the intermediate code, and transmits the movement path of the machining member as an output to the display component 40. The display component 40 is configured to use the workpiece initial parameter and the movement path of the machining member to generate at least one intermediate result for reproducing the workpiece machining program, and display the at least one intermediate result in a first display region; in one particular embodiment, the intermediate result may be a 3D image of a workpiece structural form. The display component 40 may use an open source database to generate the 3D image, e.g. an OpenGL database. Preferably, the workpiece machining program visualization apparatus further comprises: a storage component 50, configured to store in real time the intermediate code, the movement path of the machining member and the at least one intermediate result.
Fig. 3 is a display interface according to an embodiment of the present invention; as shown in fig. 3, a left-side region of the interface is used to display a workpiece machining program, and a right-side part of the interface is a first display region 100; intermediate results generated according to the workpiece machining program visualization method described above are arranged in sequence in the first display region 100, and used to simulate a structural form of a workpiece after each section of the workpiece machining program has been executed. A bottom region of the interface is a second display region 200; the second display region 200 is adjacent to the first display region 100. Step S2 may comprise an error prompt step S21; in step S21, the workpiece machining program is checked, and when error information is detected, the error information is displayed in the second display region 200 adjacent to the first display region 100. Optionally, the error information may comprise one or more of lexical errors, syntax errors, semantic errors, debugging errors, the occurrence of interference in the movement path of the machining member, and interpolation errors. In the course of program compiling, first of all the standardness of code is inspected, and the code is inspected for the presence of syntax errors, etc., in order to determine the actual work to be done by the code. If an error is found by inspection, an error report is promptly displayed; if the inspection finds no errors, the compiling of code is continued. In this way it is possible to solve the problem of an existing workpiece machining system being unable to display program errors in real time. Multiple intermediate results can be seen in real time in the first display region 100; the workpiece machining program can be checked for accuracy by means of the image display, thereby optimizing the user experience. The user can trace the source of errors via the second display region 200 located at the bottom of the user interface; this makes it easier for the user to inspect program errors, and makes error correction of the workpiece machining program more convenient and quick.
In order to save storage space and reduce the overall computation volume, visual display need not be performed for an execution result of every line of program; instead, step S4 may be executed at intervals of a certain preset number of lines of program code. For example, in one preferred embodiment, the code in the workpiece machining program may be divided into multiple program sections, e.g. such that each set of five consecutive lines of program code form one program section; in this embodiment, a three-dimensional image of the workpiece will be displayed after each set of five lines of program code has been run. By the same principle, all content of the workpiece machining program may be divided into multiple program sections in sequence from the beginning to the end, or all content of the workpiece machining program may be divided into multiple program sections in sequence from the beginning to the latest editing position. The program section may comprise a continuous program and/or program module with a preset number of lines . The program module may comprise a condition instruction, a jump instruction and an intermediate program beginning with the condition instruction and ending with the jump instruction.
Specifically, it is possible to divide the workpiece machining program into N program sections (Ci, C2.CN) from the beginning to the latest editing position, generate in real time an intermediate result (Ri, R2.RN) after each program section has been executed, and visually display in real time a machining process of the workpiece machining program from the beginning to the latest editing position. Preferably, step S4 further comprises a step S41 and a step S42; in step S41, a visualization set may be established, and on the basis of all program sections of the workpiece machining program from the beginning to the latest editing position, corresponding intermediate results (Ri,
R2.RN) of the workpiece machining program are generated, and added one by one to the visualization set, and the intermediate results are displayed in the first display region according to a sequence of the visualization set. In step S42, at the same time as each intermediate result is generated, an item of corresponding mark information Mi is generated and associated with intermediate result Ri . In one particular embodiment, the mark information comprises: a line number label of the last line of program of the program section used to generate the intermediate result; in order words, the mark information and the intermediate result are in one-to-one correspondence.
In one preferred embodiment, the workpiece machining program further comprises a step S5, i.e. storing in real time the intermediate code, the movement path of the machining member and the at least one intermediate result. Specifically, a cache of intermediate data may be established, and there is no need to repeat computation and generation of intermediate results which have already been generated; this greatly reduces the operation volume, and saves energy consumption and time. For example, in one preferred embodiment, the intermediate result Ri added most recently to the visualization set is acquired; since the mark information Mi comprises the line number label of the last line of program of the program section Ci used to generate the intermediate result Ri, the mark information Mi can be used to determine the next program section Ci+i of the workpiece machining program and generate a movement path Ti+1 of the machining member corresponding to Ci+i; and the intermediate result Ri added most recently to the visualization set and the movement path Ti+1 of the machining member are used to generate an intermediate result Ri+i for reproducing the workpiece machining program.
By the same principle it is clear that when the workpiece machining program is updated, position information of an updated program section is acquired; for example, the position information may be a line number of updated program code, the position information is compared with mark information in order to determine the corresponding intermediate result in the visualization set, and intermediate results following the corresponding intermediate result in the visualization set are generated afresh and replaced. For example, if a division method is used whereby each set of 5 lines of program code form one program section, and supposing that the 53rd line of code of the workpiece machining program is amended, i.e. one line of program in the 11th section of program is changed, then it is only necessary to start from the 11th section of program and re-compile the subsequent program, to generate a movement path of the machining member after the amendment position, a corresponding updated intermediate result Rn and all subsequent intermediate results
(Rii, Ri2.RN) ; the intermediate results (Ri, R2.Rio) already generated previously all remain unchanged, with no need for re-compiling and re-computation. Thus, when the user has amended the workpiece machining program, the user can observe in real time the change in a machining result after amendment and updating .
