SURFACE PLASTIC DEFORMING METHOD Russian patent published in 2007 - IPC B24B39/00 

FIELD: manufacturing processes in machine engineering, namely methods for finishing and strengthening blanks.

SUBSTANCE: method comprises steps of imparting speed to blank and feed motion to tool having striker in the form of similar diameter rods, wave-guide and deforming tool secured to free end of wave-guide; applying to deforming tool made of elastic material in the form of tore static and periodic pulse loads normal to worked surface of blank; mounting deforming tool at providing normal arrangement of lengthwise axis of blank and central axis of tore for rough working of blank surface or providing their parallel arrangement for finishing blank surface; applying periodic pulse load according to condition of increasing area of contact spot of tore and surface of worked blank. In zone of tore contact with worked surface of blank distance between center of circle with radius r and central axis of tore is proportional to value of periodic pulse load and elastic properties of tore material.

EFFECT: enlarged manufacturing possibilities of method.
