Edge detection technique appeared only a few decades ago, but has a lot of research on this issue. The problem of general edge detection and edge detection information after manufacturing on CNC machine at z height is relative major problem in image analysis, because of the features extracted in the process of selecting image analysis is based on the minutes. Border point, which has the sudden change of gray level. The set of boundary points forms the boundary or boundaries of the image. Basis, Base on these concepts, two methods of classical edge detection and edge detection enhancement were used. From the boundary as shown in the different height z, the deta.iled surface after machining in which show high microstructure, surface appearance and fracture patterns on the surface... were described.
