Experimental investigation of edge chipping defects in rotary ultrasonic machining of float glass

Abstract

Abstract This paper describes the results of investigation on the rotary ultrasonic machining (RUM) of the float glass with the primary objective of analyzing and remedying the edge chipping defects. The present research is conducted to ascertain the effect of various process variables viz. feed rate, ultrasonic power on edge chipping size, through an efficient statistical method, response surface methodology (RSM). In addition, optimal parametric settings have also been proposed to reduce the edge chipping defects for the benefit of practitioners. It is found that both feed rate and ultrasonic power significantly affect the edge chipping behaviour of float glass under RUM. Edge chipping size (ECS) initially decreases with increase in ultrasonic until 60% beyond which it increases for a specific feed rate. It is further observed that feed rate has direct correlation with the size of edge chipping. Statistical analysis of the measured data through ANOVA suggests that the feed rate has major contribution on edge chipping.
