Abstract

A determination of the anisotropy in the shear strength during machining of a group of free-machining steels including 1117, 11L17, and 1215 and a plain steel, 1018, is presented. The three free-machining steels are anisotropic in the as-received condition, but the nonfree-machining steel is not anisotropic. Since tensile ductility depends on inclusion content and the orientation of inclusions relative to the specimen axis, and the same is true for the shear strength during machining, then, as expected, there is a relationship between the two for the steels all at the same strength level of 50,000 psi; the effective shear strength during machining decreases with decreasing tensile ductility.
