Abstract

Background/Objectives: Last decades have witnessed a rapid growth in the development of harder, difficult and complexity to machine metals and alloys. Abrasive Water Jet Machining (AWJM) is one of the recently developed nontraditional mechanical type hybrid machining processes in processing various kinds of hard-to-cut materials. It is an economical method for heat sensitive materials that cannot be machined by processes that produce heat while machining. Machining parameters play the lead role in determining the machine economics and quality of machining. This paper investigates the prediction of MRR and SR on Aluminum, Copper and Lead alloys using the combination of Artificial Neural Network (ANN) and Fuzzy Logic (FL). Methods/Statistical Analysis: In this study, the consequence of different AWJM process parameters on Material Removal Rate (MRR) and Surface Roughness (SR) of three nonferrous alloys namely Aluminum, Copper and Lead which are machined by AWJM was experimentally performed and analyzed. According to Response Surface Methodology (RSM) design, different experiments were conducted with the combination of input parameters on these alloys. Findings: A combinational method called as Adaptive Neuro Fuzzy Inference System provides effective knowledge based training to process parameters, to make its enhancement of process performance.
