Q

the sheet metal is between a PRESSURE PAD and a BASE DIE. a WIPING DIE with a rounded corner descends at a specified clearance onto the sheet metal to bend it

when permanently deformed, the metal will still flex back somewhat due to the elastic portion of the overall deflection as the forces are removed.

LANCING configurations used as ways to attach sheet metal pieces together

A

ANGLE LANCING and BRIDGE LANCING

17
Q

BENDING or SHEARING can be done on this machine. the WIPING DIE with a sharp corner descends to bend the material into a v-shape

A

BRAKE/ BENDING BRAKE/ PRESS BRAKE

18
Q

process for bending very long lengths of sheet metal; uses a series of rollers to fold the metal strip in a series of progressive stages.

A

ROLL FORMING CONTINUOUS SEAMLESS GUTTER

19
Q

What is one example of an application of ROLL FORMING?

A

CONTINUOUS (SEAMLESS) GUTTER for houses

20
Q

can be added to the edges of sheet metal for the purpose of longitudinal stiffening and to hide a sharp edge

A

EDGE BENDS/FOLDS

21
Q

Three main categories of EDGE BENDS/FOLDS

A

FLANGES
HEMS
BEAD or CURL

22
Q

Three main categories of EDGE BENDS/FOLDS

A

FLANGES (longitudinally stiff, but not in the transverse direction.)
HEMS
BEAD or CURL

23
Q

stiffening options for flat areas (ribs - bed of a pickup truck)

A

BEADS and RIBS

24
Q

the primary process for making soda cans

A

DEEP DRAWING

25
Q

sheet metal is placed in tension and stretched over a properly shaped STRETCH BLOCK.

A

STRETCH FORMING

26
Q

the process that can reduce residual stresses, which keeps fatigue cracks closed.

A

PEEN FORMING/ SHOT PEENING

27
Q

the process necessary to increase the diameter of a tube locally along its length. the THIN-WALLED TUBE is placed inside a split die with an internal cavity such that the walls are unsupported where you want the BULGE to be.

A

BULGING

28
Q

pressurized fluid is used to expand the tube and form the BULGE

A

HYDROFORMED BULGING

29
Q

expanding gas is used to expand the tube and form the BULGE

A

EXPLOSION FORMED BULGING

30
Q

whatever is used to push the material into BULGE shape

A

BULGE MEDIUM
