Residual Stress Model for Speed-Stroke Grinding of Hardened Steel with CBN Grinding Wheels

Abstract

To be competitive, production industry demands efficient, high-quality finishing processes – requirements speed-stroke grinding promises to meet. This paper presents a preliminary residual stress model for speedstroke grinding based on superposition of mechanical and thermal analyses as verified using analogical processes. Comparison showed that results for a residual stress model and grinding experiments correlated well. This model enables robust process control achieving compressive residual stress, itself an important surface integrity feature.
