Abstract

This paper presents the results of sample processing of steel 45 (HB 170) in the green state when

applied to the warp of ultrasonic frequency for normal and tangential. Studies have shown that

under normal processing scheme does not allow to obtain high quality of the surface layer in the

processing of metals and alloys, low hardness. Use of the scheme with the introduction of ultrasonic

tangentially excludes intensive flow of material in the contact zone of interaction and provides a

significant reduction in the surface roughness, and also eliminates significant development of

plastic deformation, which leads to the formation of flow waves. Parameters of technological

impact at this circuit can control the quality of the surface layer, both geometric and physical-

mechanical characteristics.
