I need help. No matter what I do I am getting chatter on the edges of the PVC I cut. I'm using a .125 Super-O. I have tried to slowdown the feed rate. I have tried to speed it up. I have tried changing the RPM but still getting chatter. I;m getting good chip load. I wondering if it is my machine? Maybe something loose but MDF with a .25 compression endmill cuts great.
