In the field of machining of free-form surface parts with a typical complex space, a five-axis hybrid milling machine takes advantage of its unique structural form and kinematics. In this paper, this type of milling machine as the research object, according to the typical application requirements, summed up the degree of freedom of the hybrid module parallelism module requirements, In-depth theoretical research is carried out. The new parallel mechanism with configuration synthesis is applied to the design of five-axis hybrid configuration. Then the prototype of the test is developed and the milling machine prototype is used in the milling process. The aim is to promote the application of less-degree-of-freedom parallel mechanisms and the development of five-axis hybrid milling machines through theoretical research and application experiments. Through the process analysis, the requirements of modern complex surface components for processing equipment can be summarized as follows: 5-axis positioning and milling and 5-axis variable axis contour milling. The demanding conditions of the tool corner can be summarized as follows: a loading card five processing. In order to achieve the necessary flexibility and processing flexibility, the application requirements are reflected in the mix
