Abstract
Abstract: In abrasive jet machining, abrasive particles are mixed with compressed air in a closed chamber and are directed over the target surface through a nozzle. The stream of particles coming out of the nozzle with very high velocities (175-300m/s) impinges the target surface and removes the material by erosion. Typically for abrasive jet machining brittle work piece or brittle materials are machined more efficiently. In this project, the highlights are the influence of different process parameters like Pressure, Nozzle Tip Distance, and Nozzle Diameter on the Metal removal (MRR) of Epoxy Glass Fiber Composite by Abrasive jet machining. Tungsten carbide nozzles with diameters 3mm, 4mm, 5mm were considered. For this study, SiC (Silicon Carbide) abrasive with grit size of about 60µm is selected. Other parameters include Pressure (4kg/cm 2 , 6kg/cm 2 , 8kg/cm 2 ), Nozzle Tip Distance (6mm, 8mm, and 10mm) are considered. Experiments were conducted and the results were analyzed and optimized with Response Surface Methodology of optimization and adequacy of the model is evaluated using analysis of variance (ANOVA) technique.
