Function overview

Function
With this measuring cycle you can measure the dimensions of the following contour
elements on a workpiece using different measuring variants:
● Hole
● Shaft
● Groove
● Web
Measurement is performed at a specified starting angle to the abscissa of the workpiece
coordinate system.
For hole, shaft, additional measurements are performed at an indexing angle, added to the
previous angle.
This allows you to measure circle segments of a workpiece contour whose center points lie
outside the machine.
CYCLE979 can
● measure the contour elements
● perform an automatic tool offset
● correct a zero offset (ZO)
based on the differences between the center positions.
