CRITERION C CONTENTS LIST

• Required material properties are identified

• Materials are tested and compared prior to selection

• Topic 4 design language is used to describe, explain and justify choicesAll technical drawings are clear and able to be used and understood by others

• BOM reflects actual research and is accurate

• Plan of manufacture able to be understood and followed by others

1. JUSTIFIED MATERIALS CHOICES

• Explain/list the material properties and qualities required for your prototype (think topic 4)

• Test and compare materials to decide which is best (add photo evidence)
  Use topic 4 language when assessing and comparing materials (Young's modulus, stress, tension, mass, density, hardness etc)

• All chosen materials are identified in a table

• Name, properties and availability included

• Environmental impact/concerns stated

• Materials choices are justified

2.  JUSTIFIED MANUFACTURING CHOICES

• Compare suitable manufacturing methods (add photo evidence and explain)

• All Machines and tools identified in a table

• Manufacturing choices are justified

• Safety Concerns

• Name, properties, common uses and availability included

3.  DIMENSIONED PART DRAWINGS

• Orthographic line drawings (CAD or drawn) for each component/part

• Label each with a part title and scale

• All external, internal and adjoining spaces are dimensioned

4.  ASSEMBLY DRAWING

• Exploded view used in line drawing format

• Arrows and annotations explain assembly

• A parts table can also be added

5.  List of Parts (LOP)

• Isometric, orthographic or exploded view of design

• Parts are identified with numbers and arrows

• Each part has a number, name, material and function labelled

6.  BILL OF MATERIALS (BOM)

• All materials used are listed in table format

• Material use (which part it will be used for)

• Cost per common unit sold

• Amount used

• Total cost for 1 prototype for each material and total cost overall

• Brief explanation with a researched example of how buying in bulk could reduce this cost

7.  PLAN OF MANUFACTURE

• Table format, each step numbered in order

• No more than 10 words per cell

• Refers to exacting tools, materials and sizes used

• Potential quality checks identified

• Identify safety measures and concerns

• Tick box to use later - indicates step complete or not

• Utilise dimensioned drawings in steps
