Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect. However, in order to have a measure for sake of comparison, the limit drawing ratio (LDR) is taken as a measure of drawability. LDR is defined as below- For most of the sheet materials which are [...]
In last few years the use of hydrostatic pressure in forming has got greater interest of researchers mainly because of the requirement to manufacture light weight structures for automobiles. Reduction of body weight of an automobile can be achieved by using lighter gage sheets of steel or by using sheets of lighter material like aluminum alloys. In both the cases [...]
Here is a list of sheet metal forming processes:- 1. Cutting Off, Blanking, Punching and Piercing Process 2. Bending 3. Deep Drawing. 1. Cutting Off, Blanking, Punching and Piercing Processes: For almost all sheet metal components, blanking/punching or cutting off is the very first process. Cutting off: It refers to the process of shearing off across the entire width of [...]
