I am trying to turn 270 degrees of a sphere on the end of 1.125" bar stock using Type II G71 and it isn't working. I'm getting an overcutting alarm 41 for the tool nose radius compensation. Here is the program below. Any help is greatly appreciated!!! (Tool nose is .0312 with imaginary tool nose 3)
