Cylindrical/Virtual C Parameters
Chapter 30
30-3
Function
This parameter specifies the name of the machine axis that will be the park
axis during cylindrical interpolation. The park axis is used to align the mill
tool with the center-line of the rotary axis.
Important: The machine axis named as the park axis must be an axis in
the current machine configuration or configured as none.
When cylindrical interpolation is activated, the control moves the mill tool
along the park axis to the axis position specified by the Rotary Center
Park Coordinate parameter.
Once the tool is positioned at the park coordinate of the park axis, the park
axis is locked at its current position. The control will not allow any
additional park axis commands during cylindrical interpolation. This
prevents the tool from being moved off the center-line of the rotary axis
during cylindrical interpolation.

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