This paper presents a new method to determine manufacturing parameters that will optimise tooth form and geometrical accuracy when manufacturing hobs. The method provides a higher profile accuracy and proper tooth form through transversely relieved grinding on conventional grinding machines. A model for the enveloping process of tooth profiles when hobs are ground is established to eliminate the needs for computation of complex transcendental equations. The grinding surface of the grinding wheel are well controlled by a new dressing method to generate concave cutting edges on the hobs. This results in the production of drum gear tooth form that provide a better meshing contact to achieve better working condition and transmission quality of subsequently generated gears or wormgears manufactured by the hob.
