Experimentation and optimization of cutting parameters of abrasive jet cutting on AA6082 through response surface methodology

In today?s context manufacturing industries primary target is to produce the product with high quality. The important properties for the products producing high hardness, wear resistance, toughness is in high demand for various applications say marine, aeronautical or nuclear industries. The quality of making products using conventional process is quite complicated. Abrasive water jet machining is used most widely in the present development because of its machining accuracy. Due to the particles of abrasive grains, the materials get fractured in the targeted area with the much loss of kinetic energy. This cutting operation is fast and simple to remove the portion of materials more effectively. Due to the tremendous features in water jet machining technique, many researchers attention is focused towards this process by studying the varying input parameters, different abrasive mesh sizes for improvement of better machining conditions without any additional cost. In this work, machining operational parameters are to be optimized on abrasive water jet machining of AA6082 to achieve minimal surface roughness and maximum material removal rate and hardness. Cutting parameters such as abrasive feed, stand-off distance and nozzle speed are considered to optimize the AA6082 cutting through Response Surface Methodology. ? 2020 Elsevier Ltd.
