The application of aluminum alloys in automotive and aerospace industries has been growing significantly in the last 20 years. Due to their high specific strength, aluminum became a strong replacement for steel particularly at automotive manufacturing. However, to deform a complex panel part from aluminum is quite challenging specifically at cold forming .
Material flow in hot rolling is less homogeneous. Friction coefficient in hot rolling may be high-ranges from 0.2 to 0.7 [38].To sum up, there is a difference between the experimental and .clamp the blank on the die, while the punch pushes into the sheet metal. The sheet is drawn into the die hole taking the shape of the cavity. Shearing: This is nothing but cutting of sheets by shearing action. Sheet forming: Sheet metal forming involves forming and cutting operations performed on metal sheets, strips, and coils.
