The first thing to try is just a reduced DOC, maybe .08, see how that goes. Also check the pulleys on your stepper motor, make sure the grubs screws are tight and one is over the flat of the motor shaft.
Is your toolpath a contour? If so, you are cutting a slot (a cut exactly as wide as the tool), and that can be very difficult.
The usual advise is to instead create a pocket around your project that is about 50% wider than your bit (so in this case, say .350"). So it makes two passes around your project, and the worst case is a slot that is only 1 DOC deep.
HOWEVER, current versions of CC have a bug where pockets are cleared DEPTH first, so it ends up creating a slot, and then clearing the rest of the pocket. If you have it, I think previous version 729 does things correctly.
