Computer Simulation of the Cutting by Generation of Polygonal Profiles

The paper proposes a continuous method of processing the polygonal profiles, which allows processing of profiles with even and odd number of sides; this method of manufacturing of polygonal profiles implies cutting by generation (rolling). This method is based on the analogy with rack and pinion gear, and consists of the gearing motion between the semi-product and a cog rack cutter. The generation kinematics is similar to the processing of the helical-toothed wheels with planning tool. The paper aims to determine the generalized relations of the geometry of cog rack cutter geometry. Processing simulations, of the same polygonal profile, are proposed, using different geometry of the cog rack cutter; simulations of processing different polygonal profiles (with even and odd number of sides) with the same tool are also presented.
