WAYS TO ENHANCE THE EFFICIENCY OF HIGH-SPEED GEAR MACHINING OF HARDENED LARGE- MODULE GEARS

Ensuring high performance characteristics of hardened large-module gears directly depends on the parameters of their surface layer. Within this study, theoretical approaches to establishing the correlation between surface condition characteristics of gear teeth and machining parameters have been analyzed. It has been determined that the relationship between the technological conditions of gear processing and the surface layer parameters can be described by a system of analytical equations. These equations can be employed in the development of algorithms and software for selecting optimal machining modes, taking into account the required surface quality parameters that ensure the long-term performance of gear pairs. The process of plastic deformation during machining is closely related to the geometry of the cutting tool, particularly the radius of curvature of its cutting edge. Changes in this radius throughout the machining process are determined by loading conditions and the properties of the workpiece material. This influence has been analyzed considering the kinematics of tool–workpiece interaction, which allows stabilization of surface layer quality during gear manufacturing.
