Measuring principle for groove or web
The groove or web lies parallel to the axes of the workpiece coordinate system.
2 measuring points are measured with specified measuring axis _MA.
The actual value of the groove width and web width and the actual position of the groove
center and web center in relation to workpiece zero are calculated from the two measured
values. The results are entered in array _OVR[ ].
The positive direction of the axis is measured first.
Measuring principle for inside and outside rectangle
The rectangle lies parallel to the axes of the workpiece coordinate system.
The measuring cycle ascertains 2 measuring points in both axes and determines the actual
