From 3D scanning, reverse engineering to real part production of personalized car parts

  • 1 Polytechnic University of Tirana, Albania


In personalized mechanical parts production, an important issue is the functionality of the part itself in the chain of multi assembled parts. There are cases when same custom parts need to be produced by fulfilling the solution of connecting two or more elements together and creating a functional mechanical system. Personalized components that are going to feet in between two existing and functional element or systems are difficult to be produced. These difficulty in terms of mechanical solutions means, dimensional accuracy tolerances of the new part and real existing features parts. By creating these personalized middle nodes which will connect two existing elements the precision accuracy feature, like tolerances, is very important. The challenges are bigger when dealing with maximum lifespan performance while withstanding mechanical shock and minimizing fatigue destruction problems. Reducing such a challenging task the 3D scanners and reverse engineering workflow fill the gap by increasing precision and accuracy tolerances digitalization’s of existing parts, creating the reverse counterpart, and reducing time to market. In our work we show a full workflow from non-contact 3D scans, reverse engineering process, for CNC aluminium milling of the digitized part in a real application sector such as modified car application. This attempt will show the benefits of active 3D scanner by surpassing some challenges such as metallic surface reflection problem that arises during scan. In the end the entire process gives to the user all the detailed technical documentation including drawings, materials, and manufacturing instructions.
