Geichuk V. Synthesis of kinematics of the process of magnetic-abrasive machining in the ring bath

In the dissertation the scientific principles of creation of the process equipment for magnetic-abrasive machining (MAM) of complex surfaces of details in a "ring bath" with large working gaps are developed on the basis of structurally-parametrical synthesis of the kinematics of process. Functional dependences of the main quality parameters of MAM (roughness and microhardness) according to the angle of attack for the major groups of materials (tool and stainless steels, titanium alloy, brass, hard metal) were defined. The generalized mathematical model of kinematics and mathematical model of a complex estimation of intensity of magnetic-abrasive machining (MAM) are determined. The basic rules of kinematics of process of machining of the basic types of details are defined and recommendations for choice of the kinematic parameters of machining are developed. Recommendations are confirmed by results of experimental researches Methods of synthesis of structural-kinematic schemes and structural formulas of configuration of rotary machines for MAM and calculation of the main dimensions of these machines were proposed. Principles of synthesis is based on analysis of the general coordinate matrix of transformation of the mathematical model of shape-generating system of machine tool, which are chosen on the basis of the integral criterion of intensity the MAM.
