So far, this report is written by knowledge auf standard through several reference drawing and experienced contents with drawing ere die of Item. The contents about actual production is so huge that I will write about it next time. Comparatively high added value Hemming die of is important for automobile development but its not proper for producing small quantity. In the future, I believe that simple easy to correct and reasonable price hemming die will be producted

So far, this report is written by knowledge and standard through several reference drawing and experienced contents with drawing hemming die. The contents about actual design is so huge that I will write about it next time. Timing chart is important to hemming die because of link position and numbers. Timing chart need a very much design time because link number and position have to applied for each case. In this paper developed an automatic timing chart and link position by relation and Pro/Program of Pro/Engineer. The method used relation rule of design parameter for timing chart. In the future, I believe that simple easy to correct and reasonable price hemming die will be producted.
