The application of high speed stream of abrasive particles carried by a gas medium (air) through the nozzle is more obvious for the materials i.e., high sensitive and brittle using abrasive jet machine. In this present work, the parameters such as material removal rate (MRR), pressure and nozzle-tip-distance (NTD) were found with nozzle diameter 2 mm using AJM with a grain size of 20 µin with sand as abrasive. The greater accuracy and surface finish was achieved with minimum diameter and maximum depth with carbide nozzle. Since negligible heat was induced while machining the surface (glass (G), fibre glass (FG) and GI sheet (GI)), the workplace is not subjected to thermal shocks. The maximum MRR with NTD 20mm for glass is 21*10-5kg/m3 at a pressure of 8kg/cm2, for the fiber glass with NTD 15 mm the MRR is 10*10-4kg/m3 at a pressure of 7kg/cm2 and finally for the GI sheet with NTD 10 mm the MRR is 27*10-4 21*10-5kg/m3 at a pressure of 10kg/cm2.
