The roll die forming(RDF) process is new manufacturing technique for tooth parts such as drum clutch, hub clutch in vehicle transmission. The characteristic of RDF process is to deform the material using the installed roll in the die. The qualitative benefits obtained from RDF process are the increased productivity, reduced press load and increased dimension quality. In this paper, RDF process is applied to produce the hub clutch with tooth shape part. FE-simulation is conducted to confirm the metal flow according to process. Finally, the hub clutch as test product is manufactured by RDF process and comparison of dimension between test product and FE-simulation is good agreement.
