Abstract：
|
|
The objective of this paper is to study the formability of sheet metal in multi\|step pressing The Benchmark\|C of NUMISHEET99 has been simulated as an example Numerical results have been compared with experimental results made by Kim Hyung jong The influence of the blankholding gap in first deep drawing on the formability of the second reverse deep drawing has been investigated The work presented here indicates the significance of simulating the whole process of multi\|step forming
