Research on high performance machining plans on aircraft part is one of most significant methods based on the rapid growth of aviation industry. This paper proposes new fixture designs, which are based on the viewpoint of embedded and unit modes, to solve machining efficiency of typical part. A complete solution is given in this paper, and typical parts have been manufactured to validate the feasibility. It can be proved from the experimental results that this new method has a certain advantage in the aspects of fixture management and clamping efficiency, and also has high value of applications.
