Note
Turning technology
The diameter programming of the interpolation parameter for the transverse axis is not
supported with CIP in the circular-path programming. The interpolation parameter for the
transverse axis must therefore be programmed in the radius.
Examples
Example 1: Milling
In order to machine an inclined circular groove, a circle is described by specifying the
intermediate point with three interpolation parameters, and the end point with three coordinates.
