Tiivistelmä
The purpose of this thesis was to examine and develop a multipurpose Computer Numerical Controlled (CNC) device which would satisfy industrial requirements, but could also be implemented at universities for students to improve and apply their knowledge in different scopes. The topic was specifically chosen because of its close relation to a summer job at a metal factory the author completed and his personal fascination with 3D printers.
The project presented in this thesis was commissioned by HAMK University of Applied Sciences. The design and development of the prototype took place in the automation laboratory of HAMK UAS, Valkeakoski unit. Literature and product documentation established the main sources of in-formation, although online resources were used as well. At the first stage, a research was carried out concerning 3D-printing related topics, such as interpolation and G-Code. Afterwards, a suitable control and motion system needed to be found. Once a list with suitable components was established, the machine design could take place. By using the design tool Autodesk Inventor it was possible to obtain a 3D model of the device.
Following the design, a prototype was built. A number of challenges were faced as major design changes had to be performed to the prototype. Still, the resulting prototype offered essentially the same functionality as the original design. For this prototype, a metal engraving tool was used at first for testing purposes, followed by a milling or drilling tool.
All in all, the results met and even surpassed the author’s expectations. Recommended further improvements include an automated tool exchange system, additional tools, a reinforcement of the structure and the implementation of a user-friendly Human Machine Interface.
