I am not having luck programming a sphere in g-code using the G71 cycle. Starting with 4" round stock and using a 35 degree insert for finishing defined as a button tool (T=8). When roughing, I'm thinking it will have to be back turned (left to right) on the back side of the centerline. Will use a CCMT and/or DNMG for roughing. We don't have CAM for turning yet. Any help would be appreciated. My tool path needs to go over to the 3.382 dimension. The finishing 35 degree insert is positioned in a 0 degree holder and should clear the back side according to my calculations. The 1.245 dimension is already turned down from the previous operation.
