CNC Control Systems - Control Program

The control program is that part which actually controls the various elements of the CNC machine tool. It has to take into account the interactions between thecontrol system components, tooling, the machine tool mechanics, and material change throughout machining and other interactions that result in the final machine tool performance.

It should analyze the part program a few blocks ahead so that the speed of the slides can be adjusted in advance to cater for future difficulties in the path (sharp changes in direction, tight radii). The control program should fully integrate with the servo and feedback systems involved.
