As a part of UNSW Engineering program (MMAN1300 course) in a team of 6 we have designed and manufactured a prototype of a mechanical air pump.
In the first part of the course we came up with sketches of our ideas on how to create the pump and acquired essential machining and metal work skills in TAFE workshops on a weekly basis.
Later on we designed the parts of the pump in Solidworks and produced engineering drawings according to AS1100 standards.
Using the produced drawings each member of the team machined a part assigned to them. We had to communicate a lot and include some adjustments in our design as we found some complications in the machining process. That taught us that it’s very important to know the limitations of the manufacturing when you design parts in CAD. However we managed to succeed in manufacturing all parts and assembled our prototype according to the deadline.
In the end of the course we have subjected the fully assembled pump to a generic test performed by UNSW Engineering staff. Our pump was attached to a test jig and it was supposed to inflate and burst a balloon in several jig strokes. Our pump has passed the test and we got full marks.
