EFFECTS OF MATERIAL ANISOTROPY UPON THE CUTTING MECHANISM.

Abstract

The experiment was performed by orthogonal cutting of aluminum. The specific cutting force K//s showed a two cycle fluctuation, K//s gains a maximum value at 30 degree and 120 degree respectively, and a minimum value at 75 degree and about 150 degree when the inclined angle theta changes between theta and 180 degree . The relation between the shear angle phi and the inclined angle theta was in fully reverse phase to the K//s- theta curve.
