Comparative analysis of methods for cutting spur gears based on technical and economic parameters

Abstract

The results of the simulation and study of the process of cutting gears by the traditional method of hobbing and the new radial-circular method (RCM), which is carried out by a thin disk cutter, but in the conditions of continuous profile generation, as it is in gear cutting with a hob. It has been shown that due to the peculiarities of this process, its kinematics, and the structure of the disk cutter, RCM is superior to hobbing in all the parameters studied: volumetric productivity, chip thickness ratio, and cutting forces, machining time and machining costs. The higher efficiency of the radial-circular method has thus been demonstrated and the feasibility of its practical application has been confirmed.
