Ultrasonic Vibration Cutting of Extra-Hard Steels

Article Preview

Abstract:

The processing of materials with a hardness greater than 55 HRC has always required the use of unconventional or grinding methods in order to obtain the quality and precision required by the technical conditions. For these reasons, the researches of the last decades have developed an unconventional method of processing, with great precision and precision, by assisting the classic processing techniques, with forced, unamortized, low amplitude ultrasonic vibrations. The present paper presents the results of some researches regarding the processing of extradural materials, by the assisted realization of the non-cushioned, low amplitude ultrasonic vibrations. It is demonstrated that this method of processing can obtain very fine surfaces, sometimes being able to replace the grinding, with much lower costs, in terms of energy consumption and tool wear.
