Abstract

This paper examines the stress distribution in the workpiece as a function of the cutting parameters associated with orthogonal cutting. It is shown that the state of stress which prevails in the workpiece during orthogonal cutting with a tool having a rake angle α, is equivalent to that which will prevail in a semi-infinite plate when a line load is applied to its edge in tension at an angle complementary to the rake angle, measured from the plate edge outer normal in the counterclockwise direction. The effect of this stress field on the surface damage accompanying metal cutting is discussed.
