The Cutting Mechanism of an Aluminum Single Crystal based on the Crystal Slip Theory

Abstract

This paper describes the effects of the crystal orientation upon the cutting mechanism and the theoretical analysis of experimental results by the distortion method. The experiment was performed by the orthogonal cutting of an aluminum single crystal having the (001) plane and (110) plane. The single crystal was produced by the Bridgman method, and the crystal orientation was determined by the Laue X-ray back reflection method.
(1) The experimental results showed that the effects of the orientation appeared clearly on the cutting phenomenon. That is, the cutting force Ks, the shearing angle and the finished surface vary with the change in the cutting direction.
(2) It is clarified that the mechanism of the formation in the shear zone is reasonably explained by the distortion method based on the slip system of the crystal.
