Investigation of Abrasive Hydro Jet Hole Making on INCONEL-825

Abrasive waterjet (AWJ) technology is a viable production method for machining metal matrices with its own set of benefits. AWJ hole making of Inc-825, on the other hand, has several drawbacks. The quality of holes and surface morphology/integrity were investigated in this study. Inc-825 material is hydrojet hole under various operating circumstances. The impact of a few essential variables affecting striation angle by using process parameters such traverse speed (TS), abrasive hydro jet pressure (AWJP), and standoff distance (sod). There are nine trials conducted in the experimental array. The characteristic change is tabulated, and a graph is presented using Grey relation analysis (GRA) and ANOVA. The SR rating has been lowered to 3.956 μm from 4.563 μm. The MRR has also been increased from 14.256 to 16.589 mm3/min. AWJM is a fantastic option for zero thermal generation machining process, the metal matrix is increasingly being used in many applications such as space, aviation, marine, architecture, and automobiles because of its superior physical and mechanical characteristics.
