Abstract
Nickel-chromium alloy 718 has a wide range of uses in aerospace, defence, automotive, and civil engineering, among other fields. Using the Abrasive Water Jet Machining (AWJM) method to cut Inconel 718 and optimising parameters such as Abrasive mass flow rate (AMFR), Stand of Distance (SOD), and Traverse Speed, this study aims to reduce surface roughness and kerf angle (TS). Then 9 samples were chosen from a total of 27 for analysis. The machined material is subjected to CMM and surface roughness inspections in order to get the best surface roughness and kerf width values. With the aid of Grey Relation Analysis (GRA) and ANOVA, the characteristic change is tabulated and a graph is displayed. The Surface Roughness rating has been decreased from 3.489 µm to 4.687µm. Similarly, the kerf width value has been decreased from 1.983 mm to 2.559 mm. AWJM is an excellent choice for Because of its better physical and mechanical qualities, metal matrix is rapidly being employed in different applications such as space, aircraft, marine, architectural, and car sectors, despite their higher cost.
