Experiments were conducted according to Taguchi’sdesign of experiments. Analysis of variance is conducted to investigatethe influence of each parameter on responses Three controllable parame-ters of three levels are applied for determining the optimal responses Theresults revealed that NTS is a most significant factor for MRR amongthree abrasives followed by AFR and SOD, with regards to surface finishand MRR White Aluminum Oxide has emerged as a most strong abrasivefollowed by Brown Fused Alumina and Garnet. It is recommended, toachieve the better surface finish, less kerf angle and good MRR WhiteAluminum Oxide be used in place of Garnet which is mostly used by theindustry today.Keywords:GarnetWhite aluminum oxideBrown fused aluminaNozzle transverse speedAbrasive flow RateStandoff distanceKerf angleMRRTaguchiANOVA*Corresponding Author:J.S.Sidhu;E-mail: [email protected]1. IntroductionIn water jet machining water is forced at a sufficient-ly high pressure through a small orifice in a nozzle(generally of 0.2- 0.4 mm diameter), causing highacceleration of water. The potential energy of water getsconverted into kinetic energy which yields a very high jetvelocity. The high pressure of the acceleratingWater particles develop fine cracks on the material sur-face, these fine cracks propagate further under the impactof high velocity water. The extended version of WJMis AWJM. In AWJM process, the particles of abrasivesare added in the water jet in-order to enhance its cuttingability for harder materials. The AWJM are mainly of twotypes entrained and suspended type. In the entrained typethe particles are allowed to draw in the water jet therebyforming an enhanced water jet with higher velocities.In suspended type AWJM, mixture of abrasive andwater takes place before the nozzle. In present work en-trained type AWJM is used in which material is removedbyerosion action of abrasive particles at a high velocity.
