This thesis focused on listing and suggesting potential upgrades to the Bending Under Tension test machine being used in the HAMK sheet metal center. The thesis also briefly examined why such upgrades were necessary and attempted to suggest upgrades given the extremely tight budget constraints and part availability. The Bending Under Tension test machine, although being a very niche machine, served an important purpose in the research and understanding of friction during forming processes. The machine was marred with outdated electronics and was in need of an upgrade.
Friction in the forming industry is a heavily researched topic, and in almost all cases researchers were forced to build their own machines and tools. The right amount of friction during a forming process was one of the main topics of previous research teams who used the bending under tension test.
The tools for the BUT test machine in the HAMK sheet metal center, were inadequate for the task they were intended for. The tools suffered from various problems such as loose tolerances and unwanted deflections. The clamps frequently had samples slip, skew, and tear mid test.
There was a plethora of other problems which unfortunately given the time and budget were out of the scope of this thesis. However, given a higher budget and more time a new machine could definitely be constructed that could be more sustainable and efficient than the current one.
The thesis in no way aims to be the finale of improvements to Bending Under Tension test machine, rather a stepping stone to more refinement.
