Study on Improvement of Machined Surface Quality by Application of Ultrasonic

Abstract

The cutting process is one of the most basic machining processes widely used in manufacturing industries, and therefore consciously required to improve its performance in quality and productivity. In this research the ultra sonic cutting (USC) was studied to reduce the plastic flow, which is seen as the cause of the geometric error and residual stress. The experimental results of USC, compared against to the results of conventional cutting, led to the now findings of reduction in 1) the surface roughness by 70%, 2) the depth of plastically deformed layer by 50%, and 3) the working hardness by 30%.
