3.7 SETTING ZERO POINT OF THE SPINDLE NOSE

If you want to calculate a tool length, before all you have to define an origin for the spindle axis coinciding with the spindle nose. For this purpose, a presetter on the working table can be used. If it is not available, you can keep a piece of any height for presetting operations. The origin that you use for presetting tools must not be used as work piece origin. For example, you can use origin OZ9 to preset tools.

OZ9 = 0
