The ways of solving problems, currently existing in the gear cutting technology are considered in the paper. The purpose of research is to improve the technical level and the automation level of universal mechanically-driven gear milling machines by the introduction of controlled drive of one of the shaping motions, which is carried out by the radial-circular method. Using the radial-circular method in the gear treatment technology is based on the idea of separation of kinematic chains of the main motion and indexing-generating motion. This allows to substitute expensive and complicated hob cutters for shaping and cutting with thin disc cutters, based on this reduce cutting strength and power and energy costs, provide vibration stability of elastic system of the machine without increasing its weight, as well as intensify the cutting conditions and reduce machining time. Patterns of change in cutting force in treatment cycle that can be used to compensate for uneven cutting process by change in machining travel speed of the stepper motor. Upgrading the gear milling machine design and using the stepper motor provides the program control of the tool drive, improves machining accuracy and quality of gear profiles, increases the automation level and technical level of universal equipment.
