In order to get spatial complicated curved surface parts and solve the difficult problems in high-speed wire cut electronic discharge machining （WEDM）, an automatic indexing NC rotary table with multi-axis movement was designed. Then the mathematical and simulation models of spatial complicated curved surface were established and some kinds of typical motion forms were selected to simulation and processing experiment. Through detecting and comparison with the design data, it shows that the sample pieces all reach the requirements in shape and dimensional accuracy to prove the correctness of the processing and simulation models. In addition, it shows that the multi-axis movement WEDM system has high machining quality and low cost and has practical applicability.
