Abstract: As a new approach to analyze shear behaviors in the shear plane and chip-tool friction behaviors in the chip-tool contact region during an end milling process, this paper introduces a method to transform an up-end milling process to an equivalent oblique cutting process. In this approach, varying undeformed chip thicknesses and cutting forces in the up-end milling process are replaced with the equivalent of oblique cutting ones. Experimental investigations for Inconel 718 were performed to verify the presented model.

Key words: Up-end milling, Equivalent oblique cutting, Specific cutting energy
