OPTIMIZATION OF PROCESS PARAMETERS IN ROLLING OPERATION FOR MANUFACTURING OF THERMOMECHANICALLY TREATED BAR USING MINITAB AND MATLAB SOFTWARE

Abstract

At low cost, designing high-quality products and process is a challenge to the engineers. For the manufacturing of TMT bars, the critical quality parameter is yield strength. This study aims to choose the optimal variables that will achieve the needed yield strength. In this research work, the use of the Taguchi Method and the concept of DOE (Design of experiment) for optimization of Thermo Mechanical Treatment Process parameter. In the plant, readings have been taken by Taguchi Method and by using MINITAB and MATLAB Software to find optimal combination factors. For optimizing the process parameters ANOVA, S/N ratio (Signal to noise ratio), and orthogonal array have been utilized. Optimum values have been obtained with the help of graphs as well as a confirmation experiment.
