Mechanics of Orthogonal Cutting

3.1   INTRODUCTION

Many attempts have been made to analyze and understand the mechanisms involved in the cutting process that enable predictions of important machining characteristics. In the last century, several models that describe the cutting process have been developed; these models qualitatively explain the phenomena observed during metal cutting. Furthermore, they indicate the direction in which conditions should be changed to improve the cutting performance in terms of product quality and surface finish.

Due to the conflicting evidence about the nature of the deformation zone in metal cutting, two schools of thought have emerged. Some workers, such as Piispanen, Merchant, Kobayashi, and Thomsen, have ...
