Experimental Study on Ball End Finishing Milling the Inclined Surface of Hardened Steel

Abstract

A three axis CNC milling machine was used for the cutting tests on the inclined surface of the 53HRC hardened steel, the hardened steel surface for the tests were keeping a inclined angle about 200 with the horizontal plane. According to the analysis of three axial milling force in the different milling strategies and different milling parameters, the effect of the different spindle speed and milling strategies for the cutting force was studied while the ball end finishing milling the hardened surface. The results of the tests were the good reaction for the rule of the cutting force which was changing with the spindle speed n and milling strategies, in addition, the results gave the reference of selecting optimum milling parameters of ball end finishing milling.
