Constant Surface Speed

Function
Use this parameter to establish the default CSS axis. Typically you would
select an axis that is perpendicular to the center line of the rotating part.
The axis named here is used if a programmable CSS axis (P1-P9) is not
programmed in the G96 block.
If an axis perpendicular to the line of a rotating part is selected here,
motion along that axis would change the cutting tool’s distance from the
part’s center of rotation. The control then would alter the spindle rpm to
maintain the programmed surface speed.

Notes
This is a global parameter. The value set here applies to all axes.
For Dual Processing controls, this is a per process parameter. The value set
in the parameters applies to all of the axes assigned to that process. If the
CSS axis is shared it is only a CSS axis in its default process unless you
select that axis as the CSS axis in both processes.
