Extended measurement

Measuring in conjunction with a 3rd axis (Y)
If a turning machine has a 3rd axis, for technological reasons it can make sense to also use
this as a measuring axis. In this case, pre-positioning and the measuring operation are
performed in the 3rd axis (Y axis); however, the measuring result correction is entered in the
tool and WO components of the 2nd geometry axis (X axis). The 3rd axis supports the radius
and diameter programming according to the relationships of the 2nd geometry axis (X).
Note
The function of including the 3rd axis for turning machines refers to the measuring cycles
CYCLE974 and CYCLE994! This function must be enabled, see

Extended bypass options for 2-point measurement (CYCLE994)
If a turning machine has a 3rd axis, then it can also be optionally used as a bypass axis.
The bypass strategies discussed in the following can be realized using the parameter
assignment screen forms or the number of the measuring axis (Parameter S_MA).
Basis for the extended bypass strategy is that the 3rd axis has been enabled for measuring
cycles.
S_MA, multi-digit = 102
1st axis of the plane is the bypass axis (Z)
2nd axis of the plane is the measuring axis (X)
