The work part zero point is set with reference to the
machine zero point M. In most cases the machine
zero point of a CNC vertical milling machine is located
above the left corner edge of the machine table
(see figure 51).
With the operations described below the distance is
specified between the machine zero point M and the
work part zero point W in the three coordinates X, Y
and Z. These values are then entered into the CNC
control.
Procedure
Starting situation:
The work part is adjusted and firmly clamped in the
machine table. All tools are gauged to each other.
The corresponding compensation values were entered
into the CNC control. The zero setting tool is
clamped and the spindle rotation is switched on.
