If your forth axis is not controlled by the CNC but rather by programming it via its own control then there is still a way to do it. It has been a long time but I once worked a formula using a spreadsheet that converted the Y movements to changing feed rates as the X moved in conjunction with a constant RPM rotation of the rotary axis.
If this is what you are trying to achieve then I will try to dig up that file to refresh my memory. Just let me know.
