Two photos of second year work linked below: The helical gearbox is a project to consolidate CAD experience and investigate architectures that would allow a gearbox to be designed that can run with the lid removed. About 10 hours of work including peer reviews and submitting a design history file. www.nottingham.ac.uk/~epzjap1/Misc/HelicalBox.jpg The filament winder uses servo control of thread tension, a 1:4 ratio spur gearbox, all shafts with ball bearings. Each student designs from the ground up and manufactures the parts using CNC milling, FDM and manual machining/fitting. Entire project, including control system, is 60 hours. www.nottingham.ac.uk/~epzjap1/Misc/BernieWinder.jpg So RP allows production of machine elements that actually work and in timescales and costs that fit into a Mech Eng degree programme. It does not put wise heads on young shoulders but they are wiser than people who have not manufactured their mistakes.
