1
Q

A
- Addition
- Forming
- Wasting
2
Q
What are the two types of addition wood processes?
A
- Traditional Wood Joints
- Component Jointing
3
Q
Name 3 traditional wood joints and their uses
A
- 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
4
Q
Wood processes - Name 3 component jointing processes
A
- Knock-down Fittings
- Wood screws
- Coach bolt
5
Q
Define Knock down fittings and give an example
A
- 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
6
Q
Component Jointing - Wood screws
A
- 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
7
Q
Component Jointing - Coach Bolts
A
Used to combine two pieces of wood
- Will often have a squared off shape underneath to reduce rotation
- Used for fitting door locks
8
Q
Name 2 forming wood processes
A
- Lamination
- Steam Bending
9
Q
Wood forming processes - Lamination
A
- 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
10
Q
Wood forming processes - Steam bending
A
- 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
11
Q
Name 3 wood wasting processes
A
- Turning
- Milling
- Routering
12
Q
Wood Wasting Processes - Turning
A
- Uses a Lathe to spin the wood and lathe tools will then be applied by the manufacturer to waste regions
13
Q
Wood Wasting Processes - Milling
A
- 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
14
Q
Wood Wasting Processes - Routering
A
- 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)
15
Q
What are the 3 turning methods?
A
- Turning between centres
-Turning on a faceplate - Turning on a chuck
