CNC machine tools have the following functions:
1. Control function: CNC can control and the number of feed axes that can be controlled linkage.
2. Preparation function: that is, G function - the function of instructing the operation mode of the machine tool.
3. Interpolation function and fixed cycle function: The so-called interpolation function is the function of the CNC system to realize the calculation of the processing trajectory of the part contour (plane or space).
4. Feed function: the control function of the feed speed of the numerical control system.
5. Spindle function: the control function of the cutting speed of the CNC system.
6. Auxiliary function: the function used to command the auxiliary operation of the machine tool.
7. Tool management function: realize the management function of tool geometry and tool life.
