CNC machining is also called numerical control machining
Before programming, it is necessary to analyze the process of the processed parts, draw up the processing plan, select the appropriate tool, and determine the cutting parameters. In programming, some technological problems such as tool setting and machining route need to be dealt with. Therefore, the process analysis in programming is very important. When processing parts on ordinary machine tools, the operation procedure of each process is specified by the process specification or process card, and the operator processes the parts according to the steps specified in the process card. When machining parts on CNC machine tools, it is necessary to program all the technological process, technological parameters and displacement data to control the machining of machine tools. The processing technology of NC machine tool is basically the same as that of ordinary machine tool in principle, but the whole process of NC machining is automatic, so it has its own advantages
This is because the problems that need not be considered in the processing technology of ordinary machine tools, such as the arrangement of working steps in the process, the determination of tool setting point, tool changing point and processing route, can not be ignored when compiling the processing technology of CNC machine tools.
