CNC machining is a process analysis, formulating a processing scheme, selects a suitable tool, and determines the cutting amount. In programming, some process issues, such as the knife point, processing route, etc. also need to do some processing. Therefore, the process analysis in the programming is very important. When machining parts on ordinary machine tools, the operation procedure for each process is used for process procedures or process cards, and the operator is machined by the steps specified on the process card. When machining parts on CNC machine tools, all process, process parameters, and displacement data are processed into processes, and control machine tool processing. CNC machine tool processing technology is basically the same in principle, but the entire process of CNC machining is automatically carried out, so it is characteristics:
1, The content of the process is complex
This is because the CNC machine tool is more expensive than ordinary machine. If only the simplicity of the processing is economical, the more complex process is usually arranged on the CNC machine tool, even in a normal machine tool.
2, The arrangement of steps is more detailed
This is because problems do not have to be considered in the processing process of ordinary machine tools, such as the arrangement of steps in the process, the determination of the knife point, change the knife point and the processing route, can not be ignored when the CNC machine tool processing process is compiled.
3. Rely on the procedure to complete all process.
4, The CNC machining process is a directive document for CNC machine tools.
5, CNC machines are controlled by program instructions, and the whole process of processing is automatically performed by the program instruction.
6. CNC machining programs include not only the process of replacement, but also the process parameters necessary to complete the process, such as cutting amount, feed route, tool size, and motion process.
7, The numerical control is high, high processing precision, low labor intensity, strong ability to adapt to different workpieces.
