ENGM 445 Mid Term Study Set
(Homework 6)
1. Typical sheet-metal thicknesses are between
Plate
0.4 mm (1/64 in) and 6 mm (1/4 in). When
thickness exceeds the upper limit of this
range, the stock is usually re- ferred to as
which one of the following:
-bulk stock
-oversized
-plate
-thick sheet
Cold working
2. Most sheet metalworking operations are
performed as:
-cold woking
-hot working
-warm working
True
3. In a sheet-metal cutting operation used to
produce a flat part with a hole in the center, the
part itself is called a blank, and the scrap piece
that is cut out to make the hole is called a
slug.
-True
-False Shear strength
4. The cutting force in a sheet-metal blanking
operation depends on which mechanical
property of the metal?
-compressive strength
-modulus of elasticity
-shear strength
-tensile strength
