EXPERIMENTAL INVESTIGATION AND OPTIMISATION IN ABRASIVE WATER JET MACHINING OF ALUMINIUM COMPOSITE

Mechanical Engineering

The aim of the project is to investigate and optimise of aluminium composite in abrasive water jet machining. Abrasive water jet machining is an emerging machining process in which the material removal takes place due to abrasion. A stream of abrasive particles mixed with filtered water is subjected to the work surface with high velocity. Abrasive water jet machining (AWJM) is widely used in aerospace, marine and automotive industries for trimming composites. The present study is focused on the experimental research and evaluation of the abrasive water jet machining process in order to evaluate the technological factors affecting the machining quality of aluminium composite using response surface methodology. Different process parameters like Jet pressure, Traverse speed, and Standoff distance in three different levels are selected for optimization with three contravene responses. For Design of experiment L20 orthogonal array is prepared to set the input significant parameters for final product is calculated for better optimization purpose. From the study it is observed that the traverse speed have the most significant role, followed by Jet pressure and Stand off distance.
