Optimization of Process Parameters in Incremental Sheet Forming of Al7050 Using Taguchi Analysis

This is the transforming era in which human involvement is going to be eliminate day by day and computer controlled machines have to be performed all the work to remove human idleness and fatigue. Aluminium is essentially used in aircraft industry, mainly in fighter planes and space shuttles because of its high strength and very light weight. The aim of this paper is to explain the Taguchi method to find the best process parameters and improved quality results in incremental sheet forming (ISF). Taguchi technique is used to investigate the variation in number of experiments, parameters and focus on acceptance in improved quality of the workpiece. The optimum possible performance of parameters is obtained by determining the optimum combination of design factors by this technique. The present work was focused on design of experiment by using L 9 Orthogonal Array (OA) on the different steps for optimal values by conducting machining on CNC machining centre. Analysis of variance (ANOVA) is employed to investigate the characteristics and experimental results which will provide the effectiveness of this approach. MINITAB-17 software is used to plot different graphs and tables in this paper. This technology has met the current needs of industry for making prototype and model especially owning to its shorter design cycles and improved the quality of design.
