Abstract: Blade is one of key parts in wind turbine. Its shape design and airfoil selection directly affects the performance of wind turbine. This paper presented reverse redesign method of blade of large wind turbine and developed a blade airfoil automatically generating system. The redesign of blade is achieved through such processes as reverse measurement, reverse CAD modeling and blade reverse model analysis as well as determining the formula of blade section parameters. The blade airfoil automatically generating system has been applied.

Abstract: With the necessity and importance of reconstructing medical image model on the medical application and research, a variety of methods reconstructing human body tissues were introduced according to different original data and application purposes. The different reconstruction processes of human pelvic tissues, molar and incisor models are detailed. This proves the validity and feasibility of the different means.

Abstract: In view of the bottleneck of the interfaces between Forward Engineering (FE) and Reverse Engineering (RE) softwares, the method of extracting feature for hybrid modeling of FE and RE is attempted to present based on secondary development for UG NX by using VC++. The method is proved through two simple surface modeling.

Abstract: The algorithm to obtain intersecting lines from section and equidistance surface is one method of resolving the problem of obtaining NC machining procedure from points cloud data. As far as cutter paths obtained by section method are concerned, if intersecting lines using tangent plane and processed curved surface are obtained directly, it will be a quite complicated process and lead to divergent iteration operation because of inconsiderate design algorithm, and therefore it leads to the failure of obtaining intersecting lines. So the method of obtaining intersecting lines from section and equidistance surface is adopted. And this paper put forward and has realized one new algorithm. The calculation is simple and the algorithm is stable. It avoids the interference of cutting tool paths.
