In order to optimize form grinding technology of 20 CrMnTi carburized steel gear with high efficiency and precision,the rough and fine grinding orthogonal experiments were carried out considering four grinding parameters,including grinding wheel speed,work table feed speed,grinding depth and V shape groove depth. Based on grey relational analysis method,the influencing laws of grinding wheel speed,worktable feed speed and grinding depth on coarse grinding force and grinding temperature were analyzed. Based ...
