Align tool to Cycle800 on nutating table/table.

[Manofwar]

Hi all, trying to get a custom cycle up and working on a siemens 840d DMU 40 FD. But, I'm having some troubles with the tools orientation when running at anything that's not 0. on the B axis. The custom cycle is designed to interpolation cut a groove into the face of a part at any size and location. However, when the machine rotates the part to the angle desired, the spindle SPOS (or SP) commands don't track to cycle 800. They rotate to the absolute machine coordinates. Is there anyway to get the spindle to clock against the cycle 800 without doing the math for each rotation?
