COMPARATIVE STUDY OF THE EFFECT OF DWELLING THE PUNCH AT THE BDC VS WITHOUT DWELLING AT THE BDC ON THE DEEP DRAWING PROCESS BY FE SIMULATION

Since past many years the manufacturing industry has made use of the conventional presses for sheet metal forming. Many advantages as well as the limitations of the conventional presses are known by now. The servo presses came into existence many years ago but are now starting to gain popularity because of its flexible slide motion programming and other significant characteristics which are unique to the servo presses. Majority of the components in various industries are made by deep drawing sheet metal process. So these growing demands need new sheet metal forming techniques which improve the quality, increase production and save time. To be able to dwell at the BDC for some time is a unique characteristic of the servo press compared to the conventional press.
