Assessment and application of modeling mechanic parts with reverse engineering

In this study, several reverse engineering applications which mainly being used in many industrial areas have been investigated and a workflow has been formed. according to this workflow, a bus turbo unit outlet/connection with both surface and solid model capabilities has been scanned by a three dimension (3d) laser scanner integrated to a portable coordinate measuring machine (cmm) and a digital model has been created. a 1/1 scale three dimension part has been printed via computer aided design (cad) model created from the point cloud acquired from laser scanning operation. this application has been evaluated according to the workflow. therefore, it has seen that surface modelling and solid design methods can be integrated with reverse engineering software in various applications. in addition, it has seen that 3d printers can be adopt easily to the applications of reverse engineering of the parts having freeform surfaces and the use of 3d printers can be a standard part of the reverse engineering process.
