METHOD OF PARTS GEOMETRIC PARAMETERS STABILIZATION Russian patent published in 2017 - IPC B24B39/00 B23P25/00 

FIELD: machine engineering.

SUBSTANCE: plate is fixed on the support along its edge, the ultrasonic vibrations source is installed on the plate and its deformation is executed. Install the source of ultrasonic vibrations in the center of the plate surface and impose the ultrasonic oscillations and the static load to it. The plate deformation is carried out to the amount δ equal to where R and r - is respectively the outer and inner radius of the plate, mm; t - the thickness of the plate, mm; E - elasticity modulus of the plate material, MPa; μ - Poisson's ratio of the plate material; [σ_t] - the yield strength of the plate material, MPa.

EFFECT: geometric shape distortion of the plate is excluded and the quality of treatment is increased.
