ABSTRACT
From the above discussions, it can be found that the previous researches mainly focused on the modeling and analysis of the circular worm tooth profile.
Different from the above studies, this paper aims to develop a novel indexable carbide inserted blade cutting hob for the planar double-enveloping circular worm drive. After introducing the structure of the proposed cutting hob, a digital modeling method for the cutting hob based on axial tooth profile data is put forward. Then, a 3D solid model of the cutting hob with the indexable inserted blades is established. The design process and manufacturing simulation are further performed. Finally, a prototype of the cutting hob is manufactured and tested.
