Abstract

   Reverse Engineering process constitutes mainly of three stages. The first stage is the data capturing. The second stage is the fitting of this cloud of points in order to get the surface, then constructing the solid modeling. The third stage is the CNC code generation for the manufacturing of the reverse engineered part.

   Data capturing process can be done using several ways. On of the available way is the 3D laser scanning. 3D laser scanning is a very fast way for capturing the cloud of points representing the surface. It also do the job with an acceptable range of accuracy. After scanning a fitting process is required in order to obtain the representing surface of the part from the cloud of points. ImageWare is used for surface fitting and presenting the graphics of the part. The fitted part is then ready for constructing the solid model, and CNC code generation using I-DEAS SDRC.
