I am using Gibbs cam to 3d surface on a Johnford VMC with a Fanuc OM controller and am having a problem. I am trying to cut a round tapered hole 1.5 inches deep 3.75 dia. with an 8 degree taper. When I cut the hole instead of looking round, it is coming out faceted. The facets aren't much, but are enough to feel with my fingers. I have two Johnford machines with the same controllers, but they are different model machines, and I have tried it on both with the same results, so I'm pretty sure it is something in my post processor file. The post was not written specifically for these machines, but runs fine on all other applications. Any Ideas?
