AWJM Being a relatively recent machining technology, abrasive water jet machining (AWJM) uses the impact of an abrasive substance to erode the material of the work piece. An detailed literature review that is included demonstrates the possibilities of this technique. The topic of this dissertation is water jet abrasive machines. Study is now being done to determine how Process parameters such as Stand of Distance (SOD), Traverse speed, and Abrasive flow rate affect Material Removal Rate (MRR) and Surface Roughness (Ra). The strategy was based on Taguchi's process parameter optimization method. When the experiments are finished, we will determine Surface Roughness and MRR.
