Technological Restrictions on Mode Parameters of Ultrasonic Plastic Deforming

The paper considers technological restrictions that appear under real conditions of machining during ultrasonic plastic deforming. Possible defects of machining which are formed at the regimes, not suitable for the conditions described, are presented. The reasons for their appearance because of the possibilities of the technological equipment are found out. The ways of preventing the appearance of defects in developing the finishing and hardening operations as well as in preliminary machining of surfaces are suggested. (paper)
