The Analysis of Temperature during Magnetic Abrasive Finishing of Plane Surface

Magnetic Abrasive Finishing (MAF) is the process in which material is removed in such a way that the fine surface finishing is performed with the applied magnetic field on the finishing zone. The aim of this work is to study the magnetic abrasive finishing as an efficient tool for internal finishing of tubes. Material such as stainless steel, heat resistance steel, carbides and many other high strength temperature resistance alloys are very important in the aerospace, nuclear engineering and research and development sectors. In many manufacturing process it is desirable and necessary to have some knowledge on the amount of heat generation and consequently rise in temperature. For example, the temperature of the contact point of cutting tool and work piece will be determining the life of cutting tool. Similarly the subsurface damage and alteration in the metallurgical structure in the machined/ finished surface mostly depend on the interface temperature. In the present research work the process parameters of a MAF process are optimized using a very effective evolutionary algorithm termed as genetic algorithm (GA). Response Surface Methodology is applied for developing the models using the techniques of Design of Experiments and Regression Analysis by the using of MINITAB17 (statistical software) was used to plan the ANOVA (Analysis of Variance) imitate the correlation between predicted and experimental data . The software used for design of experiments is Design Expert and that for implementing GA is MATLAB. The parameters are used in this process is normal magnetic force (Fmn), cutting force (Fc), and rise in temperature (�T) is response parameters, and factors are applied voltage (V), and machining gap.
