GREY RELATION APPROACH IN ABRASIVE JET MACHINING PROCESS

摘要

Micro machining of conducting and non-conducting materials with high accuracy has great demand in industries especially in machining of ceramic, brittle materials. Abrasive Jet Machining (AJM) has shown tremendous application especially in machining of hard and brittle materials. In the present paper drilling of soda lime glass has been carried out to determine the machinability under different controlling parameters. A set of L_9 series experiments were carried out by varying process parameters such as Stand Off Distance (SOD), Silicon carbide abrasive particles mesh sizes and jet pressure. Material Removal Rate (MRR) and Radial Over Cut (ROC), were taken as the output responses and are optimised with multi objective optimisation.
