Cylindrical/Virtual C Parameters
Chapter 30
30-12
Function
This parameter specifies the name of the machine axis that is parallel to the
spindle center-line during virtual C cylindrical interpolation. This axis is
the linear axis during virtual C cylindrical interpolation and the feed axis
during virtual C end face milling.
Important: The machine axis named as the axis along the center line must
be an axis in the current machine configuration.

Notes
This parameter is used for lathe controls only.
In the dual--processing lathe, this is a per process parameter. The value set
in the parameters applies to all of the axes assigned to that process.
This feature is not available on the 9/230 control.
