Reverse engineering technology is an important means of modern product design.As a new method for absorbing the advanced technology

reverse engineering is the main means of the advanced technology.Three-dimensional CAD model reconstruction is the key step in reverse engineering.By the Laser-the RE600 III non-contact 3D laser scanner the data of the geometry of the arc cam is collected

and the process of the data acquisition is introduced in detail.Then the post processing of the data is carried out by Geomagic Studio

the result is imported in to the Pro/E and the three-dimensional solid model is reconstructing

and the deformation of the mold is detected and analyzed by the Geomagic Qualify software

and then the machining simulation is done by Mastercam

thereby

a practical method for reverse engineering of the digitization of the complex products is provided.
