Reverse engineered vacuum cleaner
Disassembled and CAD reverse engineered vacuum cleaner made in Siemens NX and Catia V5
This vacuum was made as a group assignment at Luleå University of Technology in the class M7011T - Mechanical Computer Aided Engineering, using Siemens NX. The model’s measurements were based on well thought out placements, such as screw holes, that was later referenced using NX WAVE-Link to make sure the measurements were always up to date.
Many parts of the project combined the use of Surface and Solid modelling to create A-class surfaces, such as the top part that mostly has organic shapes. All the sub-/main-/top-assemblies were correctly constrained.
A fully assembled and free model can be downloaded as .stp at grabcad https://grabcad.com/library/dammsugare-1
All renders and animations are made in Keyshot 9 with their part materials made from scratch in the node editor respectively.

Process
The whole process of making this vacuum cleaner was done by dividing it into different assemblies in a Product Breakdown System. This made sure we knew every part, correct naming, and what family of assemblies they belong to. The PBS was structured so that the three first digits followed by three zeros are assemblies e.g. 220-000, Motor Body assembly. The last three digits specified the part name under an assembly e.g. 220-001, Plastic Motor Cover.
The vacuum cleaner that was taken apart for us to be able to make exact measurements and take photos to use when modelling the 122 different parts in Siemens NX and some parts in Catia V5.
The PBS spreadsheet structure was inspired and made by Wintergatan and contain:
PBS#, Name, Completion/issues/quantity/CAD program options, Status of the part and who oversaw the making it.
