Optimization of Manufacturing Conditions for Spline of Drum Clutch Hub Taguchi Method

A large variety of metal forming processes is required in manufacturing for automotive applications. Traditionally the design process for metal forming tools is based on trial-and-error and on the skill of experienced die- makers. This approach results in high development cost and long lead-times. Especially spline of drum clutch hub requires tight dimensional accuracy in its inside diameter and gear shape because it is used as the main component for the automatic transmission. In this paper, the most desirable or feasible manufacturing conditions for spline of drum clutch hub were found or determined by using Taguchi method and FE-simulation(FORGE-3D). Taguchi's optimization approach was used to obtain the optimal parameters. The significant parameters were identified and their effects on Manufacturing of spline were studied. As a results, a confirmation experiment with the optimal levels of manufacturing parameters was carried out in order to demonstrate the effectiveness of the Taguch method.
