Basic principles for describing the process of vibratory with an external source of dynamic impact

Abstract

The modern development of mechanical engineering requires high quality manufacturing of machine parts. The production experience testifies that high requirements to the quality of surface treatment of the parts need to be improved, in particular, in the finishing and clearing operations (FCO). Progressive method of processing parts is vibratory (V) on machines with U-shaped containers. Despite the positive practical experience of vibratory using in mechanical engineering, this method faces a number of problems related to the development of its theoretical foundations: equipment and tools are still imperfect; in the initial stage are works on managing of the V process; it is insufficiently studied the mechanism of surface layer formation at V. These problems hamper further development and improvement of the vibratory, which is very effective by its technological capabilities, and limit its wider introduction into industry. Efficiency of processing is provided by the right choice of equipment, schemes, and modes of processing, types of working environments. The mass of loading in the container of the machine does not absorb all the energy transmitted by the vibratory machine, but only part of it, the other part is non-productively dissipated. Therefore, the choice of the constructive scheme of the machine, on which the redistribution of these energies depends, is a crucial step, both in its design and in the management of the machining process.
