Multi-point sheet metal forming is a relatively new and developing flexible sheet metal forming technology. In this type forming, die is separated into small discrete pins which can be arranged in height. So, this reconfigurable die meets the customer requirements mainly used in prototyping of sheet metal parts. Dies in conventional forming process are replaced with these pair of matrices of pins. In this study, the fundamental principles of multi-point forming (MPF) are examined and main parameters of this process are determined with numerical analysis. In FE modeling each pin is actively controlled to form the sheet part. Aluminum 1100 H14 with 1 mm sheet is used as workpiece material for sheet metal part and finite element simulations are employed then, differences between solid die forming and multi-point forming are indicated. Tearing and dimple formation are investigated and compared with conventional method. The results of the numerical analysis show the multi-point forming is very suitable for forming the sheet metal with complex shape.
