Abstract:
Because of its high productivity and versatility, gear hobbing has always been paid more attention in the gear manufacturing process. However, due to the complexity and particularity of the forming movement of gear hobbing, the simulation model and method should be established to assist the analysis of this process. In this paper, the CAD geometric simulation and finite element simulation research were discussed. From the aspects of chips, cutting force, cutting temperature and tool wear, the main research methods and results of scholars both at home and abroad were disscussed, the defects of the present study were analyzed, summarize and made a forecast, provide a certain reference for the research of hobbing process optimization, cutting tool life and workpiece surface quality improvement.
