Abstract

Grind-hardening is an integrated manufacturing technology of surface-quenching and grinding process. The residual stress is one of the main characteristic parameters of grinding-hardened surface quality. On the basis of the grinding-hardening test, influences of the grinding speed, the grinding depth and the feed speed on residual stress in grinding-hardened layer of 42CrMo steel were systematically studied. Basic regularities of above-mentioned grinding parameters on residual stress and its relationship with micro-hardness distribution of the hardened layer are generally revealed. The results show that compress residual stresses decrease with the grinding speed and grinding depth increasing or feed speed decreasing, whereas maximal compress residual stress and the action depth of stress rise accordingly. This study provides the theoretical and experimental foundation for actively controlling grinding-hardened surface quality.
