Gear hobbing, as any cutting process based on the rolling principle, is a signally Multiparametric and complicated gear fabrications method. Although a variety of simulating methods has been proposed, each of them somehow reduces the actual three-dimensional (3D) process to planar models, primarily for simplification reasons. The paper desribes an effective and factual simulation of gear hobbing, based on virtual inematics of solid model representing the cutting tool and the work gear. The selected approach, in contrast geometry are normal results of successive penetrations and material removal of in a commercial CAD environment, by exploiting its modeling and graphics capabilities. To generate the produced chip and gear volumes, the hobbing kinematics is directly applied in one 3D gear gap. The cutting surface of each generating positions (successive cutting teeth) formulates a 3D spatial surface, which bounds its penetrating volume into the workpiece. This surface is produced combining the relative rotations and displacements of the two engaged parts (hob and work gear). Such 3D surface “paths” are used to split the subjected volume, creating concurrently the chip and the remaining work gear solid geometries. This algorithm is supported by a universal and modular code as well as by a user friendly graphical interface, for pre-processing user interactions. The resulting cutting forces course, tool stresses, and wear development as well as the optimization of the gear hobbing process. [DOI:10.1115/1.2738947]
