Before using CNC pre-processing software to generate any type of tool path, the software must input the parameters required for machining. Which parameters are input depends on the following factors: (1) The value of the inserted tool path statement can be provided; (2) It can provide the information required for the NC pre-processing to generate the tool path; (3) It can provide multiple choices for the system to process the information. The parameters required for different machine tools are different. Table 1 lists the parameters that are often set in the four types of milling: after selecting the appropriate machining parameters, the machining position of the parts to be machined is indicated on the screen, and the CNC pre-processing software The real tool path during machining will be automatically generated, and (1) the tool editing function can be used to check and correct the tool path; (2) combined with other tool paths into a composite tool path CompositeToolpath; (3) after conversion Process the statement. As shown in Fig. 5, it is the machining tool path of the parallel indexing cam: the tool path generation process is established at the same time as the tool position file CLFILE, and the CNC post-processing can be started. Figure 6 is a part of the location file generated by the tool path on the left.
The data post processing converts the CL file into APT data for machining. For most CNC machine tools, from the lathe to the five-axis linkage machining center, the software can quickly generate, modify, and maintain the post-processing program for machining. It is used to connect the tool path and the cutting tool positioning file, and generate The interface between the machine and the machine. Suitable for horizontal/vertical lathes, punching machines and flame cutting machines, drilling machines, milling machines, three-coordinate four-axis machining centers, five-coordinate continuous machining centers.
