Development and application of WEDM multi-axis linkage machining system of space curved surface

In this paper, a WEDM multi-axis linkage machining system of space curved surface was developed, and the systemic buildup and its corresponding motion parameters were analyzed. According to the spatial analytical geometry forming principle of ruled surface, the mathematics modeling of five-axis linkage was done, and the mathematics general models of machining three-axle curved surface by five-axis linkage WEDM system were obtained. The rotary table with two sways which served as actuating mechanism and its NC system were developed, and the satisfactory work-pieces can be machined. This system can solve the problem of machining complex space curved surface, and widen the application range of HS-WEDM machine tool, and this method will be increasingly used in the fields of mould manufacture and the space curved surface machining.
