A
Cutting
2
Q

- pushing up, raising, molding or carving a surface design in relief
A
Embossing
3
Q

A
Engraving
4
Q
- one of the means by which decorations may be applied to metals
- using strong acid to cut into unprotected parts of a metal surface
A
Etching
5
Q
- one of the means by which decorations may be applied to metals
- beating down the metal surface
A
Hammering
6
Q
- one of the means by which decorations may be applied to metals
- pressing down the sides of the pattern; opposite of embossing (but used in combination with)
A
Chasing
7
Q
- process in working metal
- heating metal to restore it to its softest possible working state
A
Annealing
8
Q
- process in working metal
- to improve steel’s corrosion resistance. Metal is heated to create an oxide skin then quenched in oil
A
Bluing
9
Q
- process in working metal
- production of metal shapes by pouring molten metal into moulds
A
Casting
10
Q
- process in working metal
- forcing malleable materials through holes to produce bars, sections, or tubes
A
Extruding
11
Q
- process in working metal
- shaping hot metal by hammering
A
Forging
12
Q
- process in working metal
- producing maximum hardness in high carbon steel by heating it to bright cherry red, then quenching it in water or brine
A
Hardening
13
Q
- process in working metal
- forming sheet metal to shape with a press tool
A
Pressing
14
Q
- process in working metal
- process in which a fast revolving sheet of ductile metal is forced over a wood or metal form
A
Spinning
15
Q
- process in working metal
- removing of brittleness from steel after it is hardened, to achieve greater toughness during heating
A
Tempering
