Influence of oblique geometry of cutting inserts of finishing face mills on cutting forces

Abstract

The feasibility of using face milling for the final formation of the parts surface layer is confirmed by a large number of scientific works. At the same time, there are significant advantages of technological processes using face mills for oblique cutting, equipped with superhard materials, with a spiral-stepped arrangement of cutting inserts. This work is devoted to the study of the influence of the inclination angle of the oblique face mill cutting edge on the cutting forces when processing the workpiece flat surface made of gray cast iron and carbon tool steel using the Deform-3D program. The influence of the cutting edge inclination in the range from 0 to -45º on the smoothness of penetration of the face mill inserts into the workpiece is discussed.
