Analysis and Simulation on Cutting Morphology of Dry Hobbing

Abstract

As the cutting layer shape of hobbing has an important impact on hobbing force, temperature and tool life, this paper put forward the analysis on morphological structure of dry hobbing cutting. The research aim at the morphological shape of cutting layer, in order to give an accurate description, Solidworks is used in the process of cutting simulation and the simulation successfully show the shape of cutting layer. Then the mathematical description is used to plot two kind of geometry trajectory. The first is about the cutting edges project on the cross-section, and another is the interception lines between the cutting edges and the cylinder surface. The analysis showed that the simulation can get ideal cutting layer, and the layer is more intuitional and clear. Meanwhile, compared with the trajectory on radial section, the trajectory on cylinder surface can describe the cutting morphology more accurately and fitter with the real cutting condition.
