Experimental Investigations on Machining of Silica Tiles using Acoustic Emission Technique

Abstract

In this paper, experimental investigations on machining of silica-silica composite using PCD tip insert cutter and electrodeposited diamond mills are presented. Acoustic emission (AE) sensing was employed for on-line monitoring of machining process. The results show that the electro deposited diamond coated tools are the best suited tool for machining silica tiles. The surface texture produced by end mill with fine grit size (D301) shows fine orientation of fibers when compared to PCD tip inserts and end mill with coarse grit size under the same cutting conditions
