Turning measurement - front edge (CYCLE974)

Function
With this measuring version, workpiece dimensions can be measured at front edges and
from these offsets are derived.
The measurement result and the measurement difference can be used as follows:
● Correction of a work offset
● Offset of a tool
● Measurement without offset
Note
Extended measurement
Information on measurement in conjunction with a third axis can be found in
ChapterExtended measurement (Page 81).
Measuring principle
The measuring cycle determines the actual value of a measuring point at a front edge of the
turned part, relative to the workpiece zero.
The difference between the actual value (measured value) and a specified setpoint in the 1st
axis of the plane is calculated (for G18: Z).
An extended tool offset in the summed and setup offsets is possible.
For the tool offset, generally empirical values can be included in the calculation.
