Question

What should be the appropriate thickness of the metal sheet when it is used as a raw material for the sheet metal operations?

(a) 1 cm to 5 cm

(b) 5 cm to 10 cm

(c) 7.5 mm to 15 mm

(d) 0.4 mm to 6 mm

The question was posed to me in final exam.

I'd like to ask this question from Types of Sheet Metal Die in portion Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

Correct option is (d) 0.4 mm to 6 mm

The best explanation: The sheet metal forming and cutting operations are mainly performed on relatively thin sheets of metal. The thickness of metal sheet should be 0.4 mm to 6 mm to operate efficiently. If the thickness is more than 6 mm, then it is normally called as metal plate. The operations are generally performed as cold working.
