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.

The aim of the work was to digitize an automotive component using reverse engineering. To apply the procedures by which an automotive component can be designed. Reverse engineering belongs in the field of innovation among the first established knowledgeintensive services. Together with the advancing development of technology and utilizing of 3D scanning, the reverse engineering is becoming an important tool for accelerating the product innovation cycles and increasing the potential of lean approach and agility of development processes in Product Design. The paper illustrates the possibilities of using and experience with these tools on examples of the scanning of the geometry of the selected automotive components.

Recently, development in the 3D technology is becoming more evident. The diffusion of the acquisition systems is helped from the rapid evaluation of the information technology and Mechatronics, permitting low-cost system by using off-the-shelf hardware (webcam, projectors, etc.) for 3D scanning. This paper is focused on the development, implementation and testing of an automated low cost motorized active 3D structured light scanning system (SLS). The scanner is based on the software platform of the DAVID Laser Scanner Vision Systems GmbH’s. Advanced of basic technologies for comparing the scanned data, will show the differences in performance of the 3D data acquisition with a test to reference approach with a commercial scanning system.
