Fig. 2-8  Zeros and reference points on a turning machine 
The zero of the coordinate system MCS corresponds to M and the zero of the WCS 
corresponds to W. In the working space of the machine the reference point is defined as R 
and the toolholder reference point with T. 
2.2.2  Position of coordinate systems and reference points 
Control POWER ON 
For incremental measuring probes, the reference point must be approached each time the 
control is activated so that the control can transfer all position values to the coordinate 
system.
