• Size: The dimensions of the product, ensuring it fits its intended purpose.

CAD and CAM

• CAD (Computer Aided Design): Software used for design and prototyping.
  • Advantages: Quicker production, digital sharing, collaborative work, easier mistake correction, and copy/paste functionality.
  • Disadvantages: Cost of software, training costs, computer hacking, and power loss.
• CAM (Computer Aided Manufacture): Hardware used for manufacturing.
  • Advantages: Quicker production, identical products, and 24/7 operation.
  • Disadvantages: Cost of machines, setup costs, training costs, machine breakdown, and downtime.

Classification of Woods

• Natural woods:
  • Hardwood/Deciduous: Examples include broadleaf trees.
  • Softwood/Evergreen: Examples include evergreen trees.
• Man-made/Manufactured Wood:
  • Examples: Plywoods, Fibre Boards, Particle Boards, MDF, plywood, blockboard, chipboard, laminboard, and battenboard.

Tools and their Function

• Coping saw: Cuts intricate shapes.
• File: Flattens wooden surfaces and removes dowels and small pieces.
• Tenon saw: Makes deep accurate cuts and fast straight cuts without binding.
• Glasspaper: Smooths surfaces and wears relatively quickly.
• Marking gauge: Easily marks out lines for cutting.

Fixtures and Fittings

• Nut and bolt:
• Rivet:
• Screw:
• Nail:

Fonts

• Arial
