Effect of Pre and Post Tempering on Hole Quality of Float Glass Specimen: for Rotary Ultrasonic and Conventional Drilling
Source abstract
Abstract
In present study, a trending hybrid drilling process i.e. rotary ultrasonic machining has been used for the float glass drilling. A majorly silica based Float glass has extensively used in various engineering applications. However, hole quality associated with pre and post tempering is a major concern affecting the service span of the glass and must be minimized or avoided. Hence, first time the effect of tempering has been investigated on machined damage region. This article presents a rotary ultrasonic drilling (RUD) process to improved hole quality by reducing-edge chipping size i.e. radial chip distance (RCD). The float glass specimens have been drilled using RUD and conventional drilling (CD), and further put in a tempering oven as per industrial standards. The results showed that RUD gives better hole quality in comparison to CD. After tempering process, it is reported that average RCD is increased by 42.58% in RUD holes, whereas 43.93% of RCD is increased for CD holes. It stated that tempering having a significant impact on RCD. Also reported that RUD technique is recommendable, as before and after tempering the RCD is approx. 36.92% lesser than CD process. Clearly indicates that RCD has reduced for RUD holes that directly reduce the monetary loss.
