Abstract

Variation is the cause of defects that lead to shift the processes beyond control. Defects that reach the customers create significant problems that can result in customer dissatisfaction, resulting loss in customers and demise of an organization or business. Design of experimental technique of standard Taguchi method is used to analyze the experiments successfully. The objective of using Taguchi techniques in this research is to identify the key factors that make the greatest contribution to the variation in response parameters of interest and to ascertain those settings or values in wheel rim manufacturing. The main components manufactured by this firm are the wheel rims of automobiles. The range of diameter of wheel rims ranges from 10 inches to 30 inches and width may vary from 2.25”– 13” (inches). Through the Taguchi parametric design approach, the optimum levels of process parameters are determined. The percentage of contribution of each process parameter is determined by Analysis of variance (ANOVA) technique. Taguchi's experimental design yields optimized control factors, resulting in superior product quality and stability. It is concluded that for the bad fusion defect, the most significant factor is current (factor A) out of three factors.
