Before programming, process the parts to be processed, plan the machining plan, select the appropriate tool, and determine the amount of cutting. In programming, some process problems (such as tool points, machining routes, etc.) also need to be done. Therefore, process analysis in programming is a very important task. When machining a part on a general machine tool, the process procedure or process card is used to specify the operating procedure for each process, and the operator processes the part according to the "program" specified on the process card. When machining parts on CNC machine tools, the entire process, process parameters and displacement data to be processed are programmed into a program and recorded in digital information on control media (such as punched tape, disk, etc.). Control machine processing. It can be seen that the machining process of the CNC machine tool is basically the same as the machining process of the ordinary machine tool, but the whole process of the CNC machining is automatic, and thus has its own characteristics.
1) The content of the process is complicated. This is because CNC machine tools are more expensive than ordinary machine tools. If it is economically uneconomical to process simple processes, it is usually difficult to complete more complicated processes on CNC machine tools, even on common machine tools.
2) The arrangement of the work steps is more detailed. This is because the problems that need not be considered in the machining process of the ordinary machine tool, such as the arrangement of the steps in the process, the determination of the tool point, the tool change point and the machining route, cannot be ignored when programming the CNC machine tool.
