Based on the gear generation principle,taking the professional software as the tool,the problem of virtual hobbing simulation of involute helical gears was studied,and the virtual hobbing simulation of the entirety of gear was completed by using macros of CATIA V5.The accurate gear tooth surface was obtained by extracting and integrating tiny curved faces which were made through virtual hobbing.The method of virtual hobbing simulation of involute helical gears was accomplished.The validity of this method was validated through analyzing the tooth surface accuracy error of the model which was below 1μm between the virtual tooth surface and the theoretical tooth surface and the possible factors affecting the tooth surface accuracy during manufacturing was also discussed.It offers a fictitious 3D platform for studying on the principle of gear cutting machine’s error as well as the finite element analysis for the theoretical tooth surface and the erroneous tooth surface.
