In spite of relatively high prices, aluminum wheels rapidly replace traditional steel wheels because of light weight and stylish design. To cope with expanding aluminum wheel market, steel wheel makers try to produce skeleton typed steel wheels adopting high strength steel which are light, stylish and lowprice compared with conventional steel wheel. But skeleton typed steel wheel disks are difficult to form because of complex shapes and low drawability of high strength steel. This paper presents the drawing process design for 5-spoke skeleton steel wheel disk. Through the finite element simulation of various alternatives for multi stage drawing processes, desirable draw die designs were proposed.
