Volkov I. Increasing the efficiency of vibration mashining of parts in finishing and hardening operations

Оbject - process of vibration treatment in the U-shape containers of vibration mashine-tools. A purpose is the rise of productivity of process of treatment of details on the finishing and consolidating operations due to the choice of technological parameters of process by determination of intercommunication between the elements of construction of mashine-tool and instrument-working environment. Methods - mathematical design, conducting of experimental researches with the use of scintific positions of theory of vibroabrasive treament, theories of vibration portage, mechanics of continujus and frible envsronments, of wearproof tireless durability, metallographic. Novelty - is grounded and explored complex of terms necessary for the rise of productivity treatment of details; are developed: mathematical model and algorithm of computation of trajectory of motion of single granule, circulation speed of boundary layer of working environment, dynfmic descriptions of influencing of walls of container on a granule and working environment on the whole depending on the parameters of vibration machine-tool; principles of prognostication of productivity of process on the basis of power model, that alljws to choose rational parameters and technology of vibration treatment on the stage of planning; it is grounded and eksperimental possibility of rise of operating properties of superficial layer of details is confirmed. Result - the developed theoretical model can be used in engineering practice at setting of the modes of vibration treatment, planning or modernizatuon of equipment, the choict of instrument and development of technological processes of treatment of details; technological recommendations on the choice of the modes of treatment of details and technological processes of treatment of compound profile details are developed. Degree of introduction - technological process of treatment details with the recommended modes are inculcated on company "Avto-Electromash". The sphere of the use is machinebuilding.
