This paper presents an improved mechanistic cutting force model for the ball - end milling process. The objective is to accurately model the cutting forces for nonhorizontal and cross - feed cutter movements in 3D finishing ball - end milling. Main features of the model include : (1) a robust cut geometry identification method to establish the complicated engaged area on the cutter ; (2) a generalized algorithm to determine the undeformed chip thickness for each engaged cutting edge element; and (3) a comprehensive empirical chip - force relationship to characterize non horizontal cutting mechanics. Experimental results have shown that the present model gives excellent predictions of cutting forces in 3D ball - end milling.
