Precision Analysis of Reconstructed Aluminum Alloy Handle

Abstract

In order to carry out the error analyses of the aluminum alloy in reverse engineering, Mastercam was used to create three-dimensional (3D) parametric solid models and automatically generate NC program files. By using the generated NC program, a simulating is processed on a milling machine. The surface of the obtained product 1 was immediately scanned by a laser scanner. Using the obtained results from the laser scanner, the three-dimensional models were created in Geomagic Studio. Reanalysis of the three dimensional models, product 2 can be obtained. Finally, Error analysis was carried out by comparing the 3D scan data with the original design models. The current research demonstrates that error analysis by the present method is feasible. However, since aluminum was selected as the processing material, the scanned data is not satisfactory; contrast error is greater after reverse engineering.
