Turning measurement - outside diameter (CYCLE974, CYCLE994)

Function
With this measuring version, the outer diameter of cylindrical workpieces can be measured.
Diameter and radius programming are supported.
The measurement result (measurement difference) can be used as follows:
● Correction in the work offset (only for measuring without reversal, 1-point measurement)
● Offset of a tool
● Measurement without offset
Note
Extended measurement
Information on measurement in conjunction with a third axis can be found in Chapter
Extended measurement (Page 81).
Measuring principle
The measuring cycle determines the actual value of an inner diameter using a 1-point
measurement or 2-point measurement symmetrically around the workpiece zero (center of
rotation). The 2-point measurement is performed by reversing the spindle through 180
degree of the workpiece or by making measurements above and below the center of
rotation.
