Abstract

The research objective is to study the technological capabilities and develop methods for designing highly efficient technological processes of strengthening treatment of parts with an oscillating tool - an eccentric strengthener.
 The tasks are theoretical modeling of the the oscillating tool processing dynamics, theoretical modeling and experimental studies of forming surface roughness, the depth of the strengthened layer and the degree of parts deformation during treatment with an oscillating tool, as well as the development of a technique for designing high-efficiency technological processes. 
 A new method of machining parts by surface plastic deformation is proposed. The dependences of the influence of treatment modes, design characteristics of the equipment and physical and mechanical properties of treated part materials on the quality parameters of the surface layer (surface roughness, depth of the strengthened layer and the degree of deformation) are obtained. The dependence for determining the treatment time is presented. 
 The theoretical dependences obtained are experimentally verified and found to be adequate according to the results of experimental studies. The regularities of designing technological processes ensuring an increase in the operational properties of the machined parts are developed. An engineering calculation technique of optimal parameters of technological processes for machining parts with an oscillating tool is developed in order to increase their operational properties. A method for optimizing the technological processes of machining parts with an oscillating tool is proposed. A software product is developed that allows performing technological design using microprocessor technology.
