Analysis of Shear and Firiction Behaviors in End Milling Process

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