Abstract
Mathematical modeling with computer application is becoming more and more popular in study, development of setup, maintenance of induction heating process. It can be used to explain, demonstrate and predict the process performance of induction hardening system. Different methods used to solve the field problems. In this paper, an effective Taguchi methodology has been utilized for selection of optimum process parameters of induction hardening of EN8 D steel. Various parameters such as power and heating time have been explored by experimentation. An orthogonal array, L9 , analysis variance of ANOVA are applied study the performance characteristic of induction hardening process. Hardness has been considered as performance characteristic. Analysis of variance (ANOVA) of response variable shows a significant influence of process variables i.e. power and heating time. The experimental results shows that the predicted mathematical models suggested could describe the performance characteristics within the limits of the factors being investigated .The results of regression equations have been verified by confirmation tests. Also microstructure analysis is done for justification of hardening work.
