• What is the initial form of a design in digital design tools?

  A set of 2D sketches

  From 2D sketches to 3D CAD drawings
• What technology can be used for rapid prototyping?

  3D printing
• What does Computer Aided Engineering (CAE) enable designers to do?

  Test and analyze performance using simulations
• What are the advantages of using CAE over traditional testing?

  Greater analytical capabilities and reduced costs
• What is one benefit of using CAE in product development?

  Decreases lead time of a product
• How does CAD software assist in the design process?

  Allows creation and manipulation of designs digitally
• What is the purpose of Computer Aided Manufacture (CAM)?

  To cut out designs created in CAD
• Why is CAM often used in mass production?

  It has high initial costs but is efficient
• What is rapid prototyping?

  A family of techniques for producing models
• What is a common technique used in rapid prototyping?

  3D printing
• What is the difference between additive and subtractive manufacture?

  Additive builds up material, subtractive removes it
• What is one-off production?

  Designing and making an individual item
• What are the costs associated with one-off production?

  High time and material costs
• What is batch production?

  Producing many items of the same product
• How does batch production compare to one-off production?

  Cheaper per unit than one-off production

  Manufacturing in huge numbers using automation
• What is a disadvantage of mass production?

  High setup costs
• What is lean manufacturing focused on?

  Efficiency and reducing waste
• What are the Seven Wastes in lean manufacturing?

  Over-production, transportation, over-processing, inventory, motion, defects, waiting
• What triggers Just-in-Time (JIT) production?

  A customer order
• What is a potential issue with JIT production?

  Delays if any part is unavailable
