Design for Manufacture

Question 1

4 uses of prototypes:

Answer 1

• To learn about the design
• communicate the design
• Integration of subsystems
• Testing and providing confidence in design

Question 2

Comprehensive vs focused prototypes

Answer 2

Comprehensive:
- Implement most product attributes
- Fully operational

Focused:
- Implement main features
- investigate overall performance (estimated)

Question 3

Rapid prototyping vs additive manufacturing

Answer 3

Rapid prototyping:
-Demo pieces
- proof of concept

Additive Manufacturing:
- real, scalable manufacturing process
- low batch, high value

Question 4

Equation for cost of a manufactured part

Answer 4

Cost of Manufactured Part = Material Cost + Energy to make the part + Cost to make the Data + Ancillary Costs

Question 5

What are ancilliary costs? give examples

Answer 5

One-off or on going costs (often INDIRECT) Mahcinery, tooling, rent compliance costs, etc

Question 6

What are Data costs? give examples

Answer 6

Anything that involves “know how”: Operating machinery, manual tasks (labour), creating design (labour and software)
