Abrasive Water Jet Machining (AWJM) is one of the recent Non-traditional manufacturing technologies in which mixture of high pressure water and Abrasive particle is used to remove the surplus material without any distortion and microstructure changes. In AWJM, major problem is to produce rough on the cutting-edge during machining on circular path. The main aim of this research is to cut disc brake of automobile vehicle using AWJM to optimize surface roughness and process parameters. In this study parametric study of traverse speed, nozzle diameters, abrasive mass flow rate, and stand of distance were carried out with disc brake of material SS420 with 4 mm thickness. Experiments are performed on Karolin Machine Tool (KMT) at Param Technocrafts and JRD Technocrafts with nozzle diameter 0.25mm, 0.30mm, 0.35mm. The surface roughness is measured by using SJ 210. Optimization of surface roughness is obtained through response surface methodology. Optimum value of surface roughness is 0.45-degree, 2.356 micron obtained for stainless steel 420 materials.
