A Review on Effect and Optimization of Abrasive Water Jet Machining Process Parameters

Abrasive water jet machining is one of the recent non-traditional manufacturing technologies for material processing. It has advantages of no thermal distortion, high machining versatility, high flexibility and small cutting forces. A design of experiments approach was taken, considering variables such as water jet abrasive size, water jet pressure, abrasive flow rate, standoff distance, the angle of attack and transverse speed. And these are optimized to investigate their influence on Metal Removing Rate (MRR) and Surface Roughness (SR) of Inconel-188. Taguchi robust design analysis is employed to determine an optimal combination of process parameters. Every day scientists are developing new materials and for each new material, we need economical and efficient machining. It is also predicted that the Taguchi method is a good method for optimization of various machining parameters as it reduces the number of experiments.
