Table index
All of the subsequently described machine data, setting data and system variables with the
same index <t> belong to the same compensation table.
Compensation function
The compensation function of the cylinder error compensation is a straight line with the form:
ΔX = m*Z + b
ΔX:
m:
Z:
b:
Measuring points
To enable the control to calculate the compensation function, the error in the compensation
axis must be measured at two points on the clamped cylindrical workpiece. In the following
figure, in accordance with the machining plane G18 (Z/X) that is usual in grinding, the basic
axis is designated Z and the compensation axis, X.
