Use Cycle 1032 GRINDING WHL LENGTH COMPENSATION to define the overall length of a grinding tool. This cycle will modify compensation or basic data, depending on whether an initial dressing operation (INIT_D) was carried out or not. This cycle will insert the values automatically at the correct locations in the tool table.
If initial dressing has not been performed (INIT_D_OK = 0), then you can change the basic data. Basic data affect both grinding and dressing.
If initial dressing has already been carried out (checkbox for INIT_D is enabled), you can edit the compensation data. Compensation data affect grinding only.
