... according to the recognized features, more accurate simulation results can be obtained. The current software can visualize the extracted difficult-to-machine shape by superposing and displaying the shape left unmachined after milling simulations on the CAD model of the part. By examining this shape...

... Abstract For several years, research has been brought to reconstruct a Computer Aided Design (CAD) model from a 3D mesh or point cloud produced by scanning techniques or CAD software. This process, which recreates the geometry of a real part is called Revere Engineering (RE). In the industry...
