| Sheet metal stamping is an important manufacturing process because of its high production rate and low cost. It is a fundamental technology in automotive, heavy vehicle and aerospace manufacture. A successful sheet metal stamping is to convert an initially flat metal sheet into a useful part with the desired shape. Stamping failures consist of either tearing (excessive tension) or wrinkling (excessive compression).; A new technology, hybrid electromagnetically assisted sheet metal stamping, was developed to control the strain distribution in a stamping operation to avoid failures. By embedding electromagnetic coils in conventional forming tools, controlling of the strain distribution of parts is enabled. Different applications of this new technology to sheet metal stamping are presented. And to better understand and utilize the new technology, analytical analyses for some application are also presented. This work focuses on the practical applications of this new technology. |
