Chapter 12 - Manufacturing methods

Question 1

Name the 3 basic processes for manufacturing metals?

Answer 1

• Forming
• Joining
• Casting

Question 2

Name the 4 types of forming

Answer 2

1) Forging (wrneches & crankshafts)
2) Rolling (I-beams & rails)
3) Drawing (rods, wires & tubing)
4) Extrusion (rods & tubing)

Question 3

Name the 4 types of casting

Answer 3

1) Sand (large parts: auto engine blocks)
2) Die (High volume: low T alloys)
3) Investment (low volume, complex shapes: Jewellry)
4) Continuous (simple slab shapes)

Question 4

Name the 3 types of Joining

Answer 4

1) Powder processing (materials w/low ductility)
2) Welding (when one large part is impractical)
3) Heat affected zone (region where the microstructure has been changed)
