KINEMATIC PERTURBATIONS OF STATIONARY TRAJECTORIES OF SHAPE-GENERATING MOVEMENTS IN CUTTING DYNAMIC SYSTEM

Abstract

The mathematical simulation of the interaction of kinematic perturbations of the tool shape-generating movement trajectories and the workpiece is considered. They de-fine one of the key factors determining the parameters of part manufacturing accuracy. The data for the effect not only of the interacting dynamic subsystems parameters, but also of the geometrical parameters of the cutting tool on the perturbation movements is resulted.
