DYNAMICS OF CUTTING FORCES IN END MILLING.

Abstract

The paper explains and gives data on the variation of the cutting force in end milling at constant depth and width of cut as well as in transients like that of cutter entering the side of the workpiece. For the latter, the rather fast increase of force amplitude is demonstrated. Further on it is shown that the force responds to a change in feed rate with a time delay which may cause instability in the Adaptive Control loop.
