I've Never Set Up An Angle Head On A Cnc Verticle Mill And I'm Having A Had Time Trying Trying To Set It Up In Mastercam. I'm Only Shifting It Off 5 Degrees. In The Z Axis.

Is this an orthogonal head? If so what does the machine itself require to program the head? does it treat it as a C axis, if so then wouldn't you program it in C axis degree's?
