If you are cutting too deep or too fast, or the mill is too high speed rotation, the symptom is chatter and the vibration eventually pulls workpiece out of clamps. But recognizing that this was the problem took a while.
Even at .01" per minute, cutting 3/16" aluminum is a bit much so I wrote some gCode to cut in .05" passes.
.05" is five times as much as .01".
