Hello, I am trying to program the backside of a sphere with a cutoff tool on an Okuma Crown using the igf. If I use OD it wants to cut along the Z axis, and if I use the OD face it wants to make the arc inverted. I would like it to do some sort of LAP cycle so it rough grooves the sphere, then takes a pass on an arc to finish the sphere. Does anyone know how to program this is IGF without having to program each groove individually? TIA
