Configuring cycles
22.8 Measuring cycles and functions
Calibration data of the tool probe referred to the workpiece coordinate system
Before calibration is started, the position of the tool probe in the workpiece coordinate
system (WCS) must be roughly entered into the following general cycle setting data. In this
case, the reference point is the outer diameter or the tool length of the active tool in the
spindle. If there is no tool in the spindle, the reference points are the spindle center point and
the tool reference point at the spindle.
Note
When measuring tools, ensure that the data of the adjustable work offset or the basic
reference always correspond to the data when calibrating (measuring in WCS!).
Always make measurements and calibrate with the same adjustable work offset.
