G- STAMPING

Question 1

varied processes that can be applied to sheet metal manipulation

Answer 1

STAMPING

Question 2

sheet metal is placed over a die and then the hole is generated by a descending punch. the sheet with the hole is retained.

Answer 2

PUNCHING

Question 3

the piece of material discarded after PUNCHING

Answer 3

BLANK/SLUG

Question 4

the same process as PUNCHING, but the SLUG/BLANK is retained and the sheet is discarded

Answer 4

BLANKING

Question 5

example of a product that is both PUNCHED and BLANKED.

Answer 5

PLAIN or FLAT WASHERS

Question 6

when punching is performed multiple times in close proximity over a given area of sheet metal. can involve any size, shape, or combination of holes.

Answer 6

PERFORATING

Question 7

Another process for putting a hole of any shape through sheet metal, but it ALWAYS intersects the side of the sheet. often associated with bending operations.

Answer 7

NOTCHING

Question 8

PUNCHING that becomes NOTCHES once the sheet is subsequently sheared.

Answer 8

SEMINOTCHING

Question 9

process that uses subsequent notches to cut out areas of sheet metal (looks like caterpillar bites out of a leaf) mostly performed in workshops or in the field

Answer 9

NIBBLING

Question 10

a process that can cut thin sheet metal without generating chips or shavings; employs ROTARY KNIVES and commonly used by can openers

Answer 10

SLITTING

Question 11

a sheet metal process that combines SLITTING with LOCAL BENDING; creates sheet metal features that are out-of-plane with the surface.

Answer 11

LANCING

Question 12

creates sheet metal features that are out-of-plane with the surface, uses a pointed punch, and results in a FLANGED HOLE and NO SLUG.

Answer 12

PIERCING

Question 13

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

Answer 13

EDGE BENDING

Question 14

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

Answer 14

SPRINGBACK

Question 15

LANCING for ventilation

Answer 15

LOUVER LANCING

Question 16

LANCING configurations used as ways to attach sheet metal pieces together

Answer 16

ANGLE LANCING and BRIDGE LANCING

Question 17

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

Answer 17

BRAKE/ BENDING BRAKE/ PRESS BRAKE

Question 18

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.

Answer 18

ROLL FORMING CONTINUOUS SEAMLESS GUTTER

Question 19

What is one example of an application of ROLL FORMING?

Answer 19

CONTINUOUS (SEAMLESS) GUTTER for houses

Question 20

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

Answer 20

EDGE BENDS/FOLDS

Question 21

Three main categories of EDGE BENDS/FOLDS

Answer 21

FLANGES
HEMS
BEAD or CURL

Question 22

Three main categories of EDGE BENDS/FOLDS

Answer 22

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

Question 23

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

Answer 23

BEADS and RIBS

Question 24

the primary process for making soda cans

Answer 24

DEEP DRAWING

Question 25

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

Answer 25

STRETCH FORMING

Question 26

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

Answer 26

PEEN FORMING/ SHOT PEENING

Question 27

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.

Answer 27

BULGING

Question 28

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

Answer 28

HYDROFORMED BULGING

Question 29

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

Answer 29

EXPLOSION FORMED BULGING

Question 30

whatever is used to push the material into BULGE shape

Answer 30

BULGE MEDIUM
