Modelling the machining parameters of wire electrical discharge machining of Inconel 601 using RSM

Wire electrical discharge machining (WEDM) allowed success in the production of newer materials, especially for the aerospace and medical industries. Using WEDM technology, complicated cuts can be made through difficult-to-machine electrically conductive components. The high degree of the obtainable accuracy and the fine surface quality make WEDM valuable. The right selection of the machining conditions is the most important aspect to take into consideration in processes related to the WEDM of Inconel 601 material. Inconel is one of the recent materials that are developed to be hard, strong and temperature resistant. The present work highlights the development of mathematical models for correlating the inter-relationships of various WEDM machining parameters of Inconel 601 material such as: peak current, duty factor, wire tension and water pressure on the metal removal rate, wear ratio and surface roughness. This work has been established based on the response surface methodology (RSM). (c) 2005 Elsevier B.V. All rights reserved.
