Cylinder error compensation

5.4.6.1

Function

The cylinder error compensation is used to compensate for clamping errors for cylindrical
grinding. In this case, a shift and/or rotation of the workpiece in the machining plane is
compensated.
Contrary to sag compensation (CEC) (Page 272), on which cylinder error compensation is
based, only two interpolation points are used to define the compensation function (straight
line).
