Abstract A rapid and high-precision detection and generation for machining information of cone component is proposed in the field of processing and manufacturing.First, triangulated irregular network model is obtained by using the Delaunay Triangulation method.Then the nearest neighborhood planes of points in the cone component point cloud or its normal vectors are acquired by using least square fitting algorithm, and a mapping relationship between the normal vectors and points in the cone component point cloud is constructed.Cone angle can be obtained using the constructed mapping relationship.Finally, according to the distribution of points of the cone component point cloud in 3D coordinate system, cone height can be obtained, and radius of bottom circle can be acquired by the relation between cone angle and cine height.So high precision processing information of cone component are rapidly acquired by way of computation.The experimental results show that compared with geometric measurement method, measurement errors of cone angle, cone height, and radius of the bottom circle are deduced 77.64%, 70.53% , 73.48% respectively, and detection time are deduced 81.74%. It can realize rapid and high-precision detection and generation method for machining information of cone component.

Key words： metrology cone component reverse engineering processing information triangulated irregular network model mapping relationship
