Abstract

This paper presents a digital simulation method for the hobbing process of cylindrical gears. Based on the gear generation principle, taking the professional software as the tool, the problem of virtual hobbing simulation on involute helical gears was studied, and the virtual hobbing simulation of hobbing on the whole gear was completed by using macros of CATIA V5. The validity of this method was validated by analyzing the tooth surface accuracy error of the model which was below 0.001 mm between the virtual tooth surface and the theoretical tooth surface and the possible factors that affected the tooth surface accuracy during manufacturing were also carried on the discussion. It offers a fictitious three-D platform for studying the principle of manufacture errors of a gear-cutting machine as well as the finite element analysis between the ideal tooth surface and the erroneous tooth surface.
