NOTE
When using the spindle center compensation
described below, set the length from the tool
mounting position to the spindle center as the tool
holder offset.
- Spindle center compensation
Compensation of the spindle center is performed.
The amount of spindle center compensation is set in parameter No.
7520. Since parameter No. 7520 is an axis type parameter, the
compensation amount for three axes (X, Y, and Z) can be set in this
parameter.
