Now a days, industries need to increase the quality of machine performance in order to meet the market demand and voice of customer, otherwise the industry will lose the customers which in turn results in losing their business. This can be achieved by reducing the variations in the process by reducing the variations in the machine defects will be minimized. This paper deals with the reduction of variations in the machine with the application of six sigma tool that manufacturing of a bush(455530) component fixing between two possible moving parts which is used in vehicle suspension, to connect the various moving arms& pivot points to the chassis. DMAIC methodology is used in the industry to reach the goal.
