17-Wood Processes

Question 1

what are the three types of wood processes?

Answer 1

• Addition
• Forming
• Wasting

Question 2

What are the two types of addition wood processes?

Answer 2

• Traditional Wood Joints
• Component Jointing

Question 3

Name 3 traditional wood joints and their uses

Answer 3

• Dovetail joint: Used in boxes and drawers due to multidirectional strength
• Dowel joint: Used to form right angles, typically used in flatpack furniture
• Housing joint: A trench is cut across a piece of timber for another piece to slot into. Used in shelving units

Question 4

Wood processes - Name 3 component jointing processes

Answer 4

• Knock-down Fittings
• Wood screws
• Coach bolt

Question 5

Define Knock down fittings and give an example

Answer 5

• Standardised fittings often used in flatpack furniture as it allows for the wood to be joined without the use of complex tools
• A modesty block is an example of this, they are small polymer blocks with holes for the screws to go into

Question 6

Component Jointing - Wood screws

Answer 6

• Threaded fasteners used to join two pieces of wood
• A pilot hole that is slightly smaller than the screws diameter will needed to be drilled first so the thread can bite into the timber

Question 7

Component Jointing - Coach Bolts

Answer 7

Used to combine two pieces of wood
- Will often have a squared off shape underneath to reduce rotation
- Used for fitting door locks

Question 8

Name 2 forming wood processes

Answer 8

• Lamination
• Steam Bending

Question 9

Wood forming processes - Lamination

Answer 9

• Veneers are glued together and formed to a desired shape
• They are held in place whilst drying by either clamps and/or a vacuum bag

Question 10

Wood forming processes - Steam bending

Answer 10

• Heat and steam is applied to wood strips to make them pliable enough to be shaped around a former
• This is done by placing the wood in a steam box
• It will remain clamped in the shape until dry

Question 11

Name 3 wood wasting processes

Answer 11

• Turning
• Milling
• Routering

Question 12

Wood Wasting Processes - Turning

Answer 12

• Uses a Lathe to spin the wood and lathe tools will then be applied by the manufacturer to waste regions

Question 13

Wood Wasting Processes - Milling

Answer 13

• Rotary cutters will be held on multiple axes, the cutter can move around the workpiece to waste regions
• Slower and more limited than routering so used more for small scale production

Question 14

Wood Wasting Processes - Routering

Answer 14

• Used Rotary cutters to move around a large piece of wood to waste desired regions
• Can be human operated, or controlled by computers (CNC routers)

Question 15

What are the 3 turning methods?

Answer 15

• Turning between centres
  -Turning on a faceplate
• Turning on a chuck

Question 16

Wood Wasting Processes - Turning between centres

Answer 16

• Wood is held at both ends
• Used to make things like table legs

Question 17

Wood Wasting Processes - Turning on a faceplate

Answer 17

• Wood is held on just one side, often used to turn bowls

Question 18

Wood Wasting Processes - Turning in a chuck

Answer 18

• Can grip onto a smaller surface of wood
• Often used to hold the small base of a bowl so the interior can be hollowed out
