For workpiece measurement with tool offset or correction in the work offset, additional
parameters are displayed, see Additional result parameters (Page 342).
3.2.6
Turning measurement - inside diameter (CYCLE974, CYCLE994)
Function
With this measuring variant, the inside diameter of cylindrical workpieces can be measured.
The diameter and radius programming are supported.
The measurement result (measurement difference) can be used as follows:
● Correction in the work offset (only for 1-point measurements)
● Offset of a tool
● Measurement without offset
Note
Extended measurement
Information on measurement in conjunction with a third axis can be found in Section Extended
measurement (Page 105).
Measuring principle
The measuring cycle determines the actual value of an inside 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 degrees
of the workpiece or by making measurements above and below the center of rotation.
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.
