Abstract

Abrasive water jet machining (AWJM) is a non-conventional machining process in which removal of material takes place by impact erosion of high pressure, high velocity of water and entrained high velocity of grit abrasives on a work piece. The purpose of the investigation is to find out the interaction between parameters of AWJM towards the surface roughness during cutting process on aluminium work piece. The experimental approach was based on Taguchi‟s method; a design of experiment to select the best combination of control parameters so that the product or process is most robust with respect to noise factors for effective machining process. The focused AWJM parameters in this experiment are Material Thickness and Nozzle distance. The method of orthogonal array in Taguchi‟s method will be used to vary the parameter respectively and for each combination, experiments will be conduct. With the help of Minitab 17, the result of surface roughness was organized and analyzed using Taguchi DOE features. The optimum parameter combination was identified by the help of graphical method and the confirmation experiments were carried out using 1-sample T-test statistical method. From the experiment, combination parameter of 5mm nozzle height and 15mm material thickness give the smoothest surface roughness for Mach 2 1313b AWJM.
