412 Influence of Material Properties and the Initial Temperature on Abrasive Grain Machining Processes

Abstract

The influence of material properties of the workpiece SK-5 on the orthogonal machining processes with negative large rake angle are investigated through the finite element analysis. The analysis shows that the material properties have a great influence on the machining processes, but that a critical uncut chip thickness, under which chip forms with great difficulty, changes complicatedly when material properties including the strain hardening exponent, yield stress, thermal conductivity, and initial temperature, are changed.
