Information Processing Of CNC Devices in CNC Machine Tools

The input device transmits machining information to the CNC unit, compiles it into information that can be recognized by the computer, and the information processing part gradually stores and processes it according to the control program's regulations. After that, the output unit sends position and speed instructions to the servo system and the main motion control part. The input data of the CNC system includes: contour information of the parts (starting point, ending point, straight line, arc, etc.), machining speed, and other auxiliary machining information (such as tool change, speed change, coolant switch, etc.). The purpose of data processing is to complete the preparation work before interpolation operation. The data processing program also includes tool radius compensation, speed calculation, and processing of auxiliary functions.
