Abstract
This paper presents a study on spiral bevel gear (SBGs) manufacturing method based on subdivision surface modeling scheme. The explicit nominal surface descriptions for both gears and pinions have been first developed based on gear generative motions. Then a group of key points on the tooth surface are selected as seed points (starting points) for a subdivision surface. From a given manufacturing precision criteria, a subdivision surface can be generated with a limited number of iterations during a subdivision surface modeling. This new surface modeling technique can be used for manufacturing (SBGs) with a general numerical control machine and a tool cutter in a flexible manufacturing environment. The experimental evaluation has been carried out and indicated that the subdivision surface-based SBG manufacturing method has advantages in high precise SBG manufacturing and precision control.
