Abstract: The problems of low grinding efficiency and twisty tooth trace crowning were existed in the process of form grinding helical gears. Through analyzing its property, the influencing law of grinding parameters on contact line was summarized, and the conclusion that the effect of grinding wheel setting angle predominated in grinding parameters was obtained. According to the law, the relationship between grinding quality of helical wheel and contact line was studied. In the condition of no grinding interference, the numerical simulation algorithm was used to optimize the grinding wheel setting angle, and control the contact line's formation by adjusting grinding wheel setting angles, thus the optimization for contact line was realized. A practical case was given to prove that the optimization method could effectively improve from grinding efficiency and crowning precision.

Key words: form grinding, contact line, grinding wheel setting angle, efficiency and precision
