The complex surface is modeled by triangular surface, B-spline or non-uniform rational B-spline first and then the planing of the cutter is followed in reverse engineering. But this require CAD/CAM software and operator’s experiene. Because of this，the research on direct NC cutter generation from point cloud have become the focus of research in reverse engineering. The normal，curvature，surface vary et al parameters are calculated by principle component analysis method and so on, which define the local feature of the surface hidden in the point cloud. Then，based on local feature，point cloud is simplified. It is proved that two points with minimal orientation-distance on a pair of smooth surfaces are conjugate points. Thus the conjugate problem between the tool surface and the part surface is converted into optimization process of orientation-distance function. The cutter trace and the cutter interference are achieved by local and global optization of the orientation-distance function.

National handcrafts are well-known at home and Abroad for their fine ingredients, exquisite blending of colors, and excellent skilled shaping and painting. What is more, they have great value and are deeply popular with people around the world. National handcrafts, as a cultural crystallization, must be protected. In order to better realize the protection, we try to apply the technology of reverse engineering to the protection. This article mainly takes a handcraft, Yan Zi YU (meaning “swallow fish”), as an example to expound and demonstrate the process of reverse engineering technology. During this process, by using scanning technology of reverse engineering, the collection and splicing of the point cloud data, the theoretical analysis of the NURBS surface in the reconstruction phase, and other practical operations in other stages, reverse engineering can be used to regenerate 3D modal data of the swallow fish and to inspect and analyse the errors in it through Geomagic Quality to ensure that the new model meets the precision requirements. Therefore, the reverse engineering technology can be completely applied to the protection of national handcrafts so that they can fully demonstrate their own value and function. If the precision of reverse engineering detection can reach nanometric level, a breakthrough will promote the protection of cultural relics.
