UMC 750 facing with C Axis

[Tony Davis]

I am trying to face a large aluminum plate on a UMC 750. The plate is 25.5" in diameter so I cant just face it normally because I don't have enough travel in X.

I am trying to travel in X to move across the plate while rotating the C Axis. I have done it before, but for the life of me I cant find the program and cant remember how I did it.

Help please

Sounds like axis substitution will work? I've only used it on an A axis rotary indexer. This thread might help you out, my guy, even uses the same machine as you are on

Easiest way to do this is draw a spiral on the face, use a contour tool path driven from that spiral and turn on axis substitution.
