Practical Application of Reverse Engineering for Elements with Free-Form Surfaces

In this paper the reverse modelling process was used to mapping and reconstruction the geometric characteristics of element with free-form surfaces as virtual CAD model. Some basic approach in reverse modelling process in middle range standard parametric 3D modeler such as SolidWorks system were presented. The digitizing process was performed on the coordinate measuring machine. Using surface-solid modelling tools the virtual solid models were carried out. There was based on prepare 3D curves from point cloud as a sectional profiles. In next step, based on 3D feature-based model, various CAx applications can be realized. In this case an abrasive wear of rotor blade was estimated.
