Use CCG software to allow the execution of part programs which have been generated with the CCG compiler library. Preliminary the machine tool builder has to integrate the corresponding library into the SINUMERIK Operate. The CCG software itself is installed on the SINUMERIK PCU/SIMATIC IPC or on an external PC.

The machine operator uses the CCG compiler to generate part programs in the polynomial format to allow machining of non-circular contours on a cylindrical grinding machine. The lift curves commonly used today, which describe the desired final contour in polar coordinates, are used as the input data for programming and generating a complete part program under SINUMERIK Operate.

The technology data, i.e., the number of infeed revolutions, allowance, sparking-out revolutions, angle of infeed and velocities, are parameterized and taken into account when the part program is generated. The generated contour is not dependent on the tool (grinding wheel) radius due to radius compensation (G41/G42) in the Sinumerik CNC.
