It should include every detail required for your solution to be manufactured in industry/ commercially
It should be:
-
centred on identified requirements (both stakeholder and technical)
-
accurate, clear and specific (not vague or generic)
-
explicit (can’t be misunderstood)
-
measurable (it will include numerical/quantitative data, for example, dimensions, tolerances)
-
justified (include reasoning)
-
approved by users and stakeholders
It should include:
-
A formal assembly drawing
-
working drawings for each part/ component
-
material information (including costs)
-
dimensions
-
tolerances
-
exploded drawings/ animations
-
manufacturing details (order and processes) - PLANNING
-
details of bought in components/ standardised components
-
As much CAD detail as possible
-
Parts drawing/ list
for design engineering it should also include

It should also include:
Planning details/ diagrams to show details of manufacture
information about QA and QC

Once you have worked out how much material you will be using, you can work out how much it will cost for your project. (in college build).
Use the following sites to help (this is where we get out materials from):
Metals: K&M Wholesales
Timbers: Howarth Tibmber
Plastics: Technology Supplies
Electronics: Kitronic
We do use other suppliers on occasions - please ask if you are not sure where to look
