You can also use all manual touch probe cycles,
except the corner probing cycle and plane probing
cycle, in Turning mode. Observe that in Turning mode
all measured data in the X coordinate are calculated
and displayed as diameter values.
To use the touch probe in Turning mode you should
separately calibrate the touch probe in Turning mode.
Because the basic setting of the turning spindle in
Milling mode and Turning mode may deviate, you
should calibrate the touch probe without center
offset. You can create additional tool data for this
purpose, e.g. as an indexed tool.
For more information about the touch probe table,
refer to the User’s Manual for Cycle Programming.
