7.3 Miscellaneous Functions for
Coordinate Data
Programming machine-referenced coordinates:
M91/M92
Scale reference point
On the scale, a reference mark indicates the position of the scale
reference point.
Machine datum
The machine datum is required for the following tasks:
■
Defining the limits of traverse (software limit switches)
■
Moving to machine-referenced positions (such as tool change
positions)
■
Setting the workpiece datum
X (Z,Y)
