Efficient Use of Materials

• What do systems do profesional wood workers often use to plan out how to cut multiple parts from MDF or Plywood

  Softwares
• Why do profesional wood workers often use software to plan out how to cut multiple parts from MDF or Plywood

  To ensure parts are NESTED economically and there aren't too many ususable leftovers 
• What can a designer do to reduce the amount of off-cuts left over

  See if they can modify their dimensions
• Why do blow/rotaion moulded items result in less waste than injection moulded items

  Blow/rotation moulded:

  Hollow = less manterial used

  One-piece moulding = strong

  Injection moulding

  At least two parts so welding/adhesive joining of some sort is needed
• What is another word for bending strength in wood

  Flexural strength
• Which design movement encouraged the movement towards economy of materials

  Bauhaus
• What are cams


  Specially shaped discs that revolve and press against other parts of the mechanism to make them move as required
• What are CNC machines used for

  When a range of different parts need to be programmed and manufactured in a relatively short time.

  This makes their flexibility invaluable 
• How has the adoption of Computer systems benefited the design and manufacturing process 

  It hhas provided the capacity for manufacturers to produce in bulk items that can then have bespoke elements incorporated in their design.

  Customers can have access to personalised goods without paying the premium price usually associated with one-off 
• What are some examples of products manufactured in bulk with bespoke elements

  Sports shoes

  Computers

  Cars
