Hi
I am planning to make camshafts for model ic engine. and would like to use rotary table to mill lobes.

How do I contol the 4th axis by degrees,  i.e. make a cut in Y direction, return, rotate table 10 deg make next Y cut and so on.

Thought of useing gear cut wizard but can't figure a way of adapting it.

Anyone got any thoughts? Thanks

Mike
