Abstract
In this study a 3-D automatic die design supporting system for a bonnet panel has been developed using Pro/ROGRAM of the widespread CAD software Pro/ENGINEER A standard drawing die was defined in terms of the punch profile, the die face geometry, and the blank sheet size. The strip layout of a trimming die was defined, in addition, in terms of the trimming line and the locations of scrap cutters. Necessary relations for each design step are formulated and rules for bottom-up type 3-D die design were set up for the automatic design of drawing and trimming dies of a bonnet. With the input geometric data of punch profile, die face, and blank sheet, this 3-D design supporting system could complete the basic design process, in case of the bonnet drawing die, in a time 78% shorter than that required by a typical 2-D CAD system. The new design system showed remarkable design efficiency also when it was applied to the case of redesign and modification of the previous standard output for a different car type.
