Abstract: Abrasive Water Jet Machining is an effective technology for processing various materials. In AWJM process the work piece material is removed by impact erosion of high velocity jet of water mixed with abrasive particles. For present work three parameters namely traverse speed, standoff distance, abrasive flow rate are considered as input parameters with three levels and Taguchi’s L9 Orthogonal Array (OA) was considered for experimentation. In this work Titanium Alloy Grade 5 was considered work piece material and Garnet 80mesh as abrasive particle. The relationship between control parameters and Output parameter (MRR and Ra) is developed by means of linear regression.
