Reverse Engineering (RE) involves the use of techniques aimed to retrieve information about manufactured products, not only regarding geometries, but also materials and functionality. Today, even if several RE techniques are known, many of them still leave the object unusable to analyze. Nevertheless, other alternatives to this problem allows for obtaining a Digital or Virtual Model (VM) via the three-dimensional scanning. Getting the VM of an item, via scanning or not, can offer many possibilities to digital analysis (FEM). Furthermore, starting from VM, it is possible to achieve the physical reproduction of an element, part or workpiece-in the same or different materials-using Additive Manufacturing (AM) technologies. This enables to improve the product through a redesign process. In this paper, a RE based methodology is proposed for redesigning a tool for contour milling, after comparing different microscopy based techniques, 3D-Scanner tools and CAD-CAGD utilities for generating a Virtual Model of the newly designed mill.

“…Nowadays, non-contact measuring systems are rising in engineering metrology due to their efficiency. In particular, when measuring parts could not be measured with coordinate measuring machines or could be measured very complicated [3]. As a non-contact measuring system, the ATOS Triple Scan System from GOM is used.…”

C omponent deviations between as-designed and as-built as a result of deformations in the production process lead to significant cost increasing during assembly. After quality inspection, components are provisionally preassembled to determine their matching accuracy. Components with an acceptable tolerance range are then assembled. Otherwise costly reworks are required. Subsequently, the preassembly process is repeated until acceptable assembly tolerances are achieved. To avoid this time-consuming and costly process loop, a flexible mounting frame coupled with a real-time measuring system is used to optimize the assembly process. The flexible mounting frame can be applied for many applications where components are to be aligned and mounted. This flexible mounting frame allows the realization of exact shape and acceptable position tolerances. The mounting frame consists of telescopic carbon fiber reinforced polymer (CFRP) tubes, linear actuators and suctions grippers. Linear actuators deform the component in the elastic range. Connected vacuum suction grippers hold the component securely to the mounting frame. The individually configurable joining device compensates manufacturing deviations during assembly in the elastic range. This is realized through a real time 3-D surface measuring system that assists in controlling a variable number of actuators. The geometric deviations are detected contactless by an external measuring system. This system provides the required measurements to control the actuators. By decoupling the measuring method from the manipulator, the system design can be kept very simple without compromising accuracy. Furthermore, the frame is mounted on a mobile robot platform. The applied mobile robot platform consists of the mobile platform (KUKA omniMove) and an industrial robot (KR QUANTEC 150 R3300 prime K). By using such mobile robot, the system can be universally used. Moreover, components can be brought into the assembly position by contour optimized elastic deformation. This novel implementation of flexibly pick up and precisely mounting system results in a more efficient and faster assembly.

“…As a result, some studies focused on determining the best scanning procedure in order to implement the scanning process on the related parts [9]. These line of works also managed to perform the comparison between the white light and blue light scanner [10,11]. The commercial software packages and 3D scanners were also tested and compared in order to assess their performance [9,12].…”

Abstract. Reverse engineering (RE) process is capable of producing CAD models from the existing part without the need of a blueprints or CAD drawing. One of the method to implement RE is via 3D scanning and the main goal is to produce CAD files that have the highest accuracy possible when compared to the actual parts. Any effort to improve the 3D scanning process should be encouraged because it will save a lot of time and expenses. As a result, this research tends to investigate the effects of surface parameters (Percentage of triangles and Grids resolution) to the performance of RE. Design of Experiments (DOE) method was used and the responses are measured in terms of File size and Error percentage. From the results, it is very interesting to note that the percentage of triangles does not have a significant effect to the file size but plays a major role in minimizing the dimension error. The grids resolution has the significant effects to the file size and error percentage. It can also be concluded that in order to get the best RE performance, the percentage of triangles and file size should be set to maximum. This will ensure that the generated CAD files will have the highest accuracy and from here, high quality products can be made from the RE process.
