This function refers to the number of axes that can be controlled by CNC and controlled simultaneously. For the axes of CNC machine movement there are moving axes and rotary axes, there are basic axes and additional axes. Generally, CNC lathes only need 2 shafts to control at the same time. CNC milling machines, CNC boring machines and machining centers require 3 or more control axes. The number of axes controlled at the same time can be 2 axes or 3 axes depending on the application. CNC machines that machine surfaces in space require more than 3 simultaneous control axes. The more the number of axes controlled, especially the more axes are controlled at the same time, the more complex the CNC controller becomes, and the more difficult it is to program multi-axis linkage parts.
