Effect of abrasive water jet turning AWJT parameter setting on surface finish of Inconel 718

Abstract

This research article aims at comparing the cutting performance of Inconel 718 during abrasive waterjet turning (AWJT). In this study, the various combination processing parameters were performed namely; depth of cut (DOC), traverse speed, and rotational speed. Three factors and two levels of full factorial involving 8 experimental runs were done during this study. This design of the experimental approach is to establish a correlation between controlled parameters input and experimental outputs. The response to be evaluated is surface roughness. The significance of AWJT parameters on this surface roughness was determined statistically using the analysis of variance method. The experimental results have revealed the surface quality of the cylindrical surface was extremely affected by the depth of cut followed by interaction between traverse speed and rotational speed. The optimum parameter set in minimizing surface finish is DOC 0.3 mm, traverse speed of 3 mm/min, and rotational speed of 90 RPM. This knowledge obtained from these results and optimization provides information for industrial applications.
