Analysis and Optimization of Process Parameters for Kerf Identification in Abrasive Jet Machining of Hastelloy: A Software-Based Approach Using ANOVA

Abstract

A software-based approach, leveraging Analysis of Variance (ANOVA), is employed to analyze the influence of different process variables on kerf width and depth. AJM (Abrasive jet machining) has been widely utilized to cut diverse materials. It has been utilized for challenging-to-machine materials, primarily metals, employed in diverse industrial procedures within the fabrication sector. An extensive knowledge of the systems governing its process of cutting is necessary for ascertaining its effective application, given its numerous uses. The chemical, marine, and aerospace industries are seeing a sharp rise in demand for micro goods. Here, the super alloys that are strong and resistant to corrosion are crucial. Hastelloy is an alloy that can be machined using AJM but it is hard to do so using regular methods. On the AJM test rig, a Hastelloy C276 sheet having a 1 mm thickness was drilled with the help of various process parameters. This paper presents the RSM methodology for the improvement of the process parameters of Hastelloy C276 abrasive jet machining. The ANOVA(Analysis of Variance) and RSM Analysis were utilized to compare the outcomes. L15 Orthogonal Array for KERF experiments are carried out at various levels.
