Paper Title:
Formation and Control of 40Cr Grind-Hardening
  Abstract

Grind-hardening machining is not only a complex process coupling mechanical, dynamical and thermal effects, but a process containing distinct changes of microstructure and properties of the workpiece grinded surface layer. Under the defined experimental conditions, an empirical formula was constituted to describe the relation between hardened layer depth and grinding parameter of grind-hardening layer, and the multi-parametric optimization was conducted. A commercial FEM software package was used to simulate the grind-hardening process. The distribution and variation characteristics of the temperature and microstructure in the grinded surface layer of workpiece were obtained and the forming mechanism of the grind-hardened layer is revealed.
