The development of computer technology has enabled it to be introduced to machine tools. The widespread use of CNC machine tools has resulted in a rapid development of the processing industry. So far, obtaining the profile of the curve has required the use of a complicated machine tool kinematic design, or it has been impossible to implement it otherwise than by copying. The numerical control of machine tools is based on the mathematical description of motion. This provides the capability to
