Please revise this program using Cutter Comp.

1. I am trying to mill the O.D. of a 4.0" diameter arc. Using a clock for an
example, the cutter will start at the 8 (cutting in the clockwise direction) and
end at the 4.
2. I will be using a .750 diameter end mill.

Many Thanks,

Bob

The D99 is an offset like H1 H48, it can be any available offset (D58 D5 D74). Make sure it is not also used as a H offset.
The G41 needs an entrance cut to take effect, 1.000" on the Y is way more then needed but will work. The entrance cut can be in any axis or a combination, try 0.100".
