I'm using MasterCam X2 and I'm programming a 1.720 X 1.720 square. The CNC Lathe I'm using is a Mori Seiki SL-200 with live tooling. When MasterCam spits out the code it looks a little something like this. (No I don't have Y - Axis)

After I machine the part the part comes out with a bad finish. Its not tool chatter or part chatter. The finish looks wavy. Can somebody tell me why the finish is coming out like that and is there a fix?

Many Thanks!
