M instruction of NC machining center is an auxiliary instruction in NC machining. According to the different machine tool manufacturers, the M instruction of different machine tools is different. Common M commands are listed below.
M00 program pauses, M0 1 chooses to stop, M02 program ends, M03 spindle rotates forward, M04 spindle reverses, M05 spindle stops, M06 tool changes, M08 cools, M09 cools, M 18 spindle orients, M 19 spindle orients, M22 tool magazine returns, and M23 tool magazine enters the spindle.
Extended data
Generally speaking, the technological procedures of NC machine tool machining and traditional machine tool machining are the same, but there have also been obvious changes. Machining method of controlling the displacement of parts and tools with digital information. It is an effective way to solve the problems of variety, small batch, complex shape and high precision of parts and realize efficient automatic machining.
Machine tools controlled by computers and computers used to control machine tools, whether special computers or general computers, are collectively referred to as numerical control systems. The movement and auxiliary actions of CNC machine tools are controlled by instructions issued by CNC system.
The instructions of CNC system are written by programmers according to the material of workpiece, processing requirements, the characteristics of machine tools and the instruction format (CNC language or symbol) specified by the system. According to the program instructions, the numerical control system sends operation or termination information to the servo device and other functional components to control various movements of the machine tool. When the machining process of the parts is completed, the machine tool will automatically stop.
