Research and Development of Precision HS-WEDM

This paper deals with the theoretical analysis and experiments for the main factors that affect the machining accuracy in HS-WEDM, and promotes the technical solutions for precision HS-WEDM while devotes four key technologies to develop quality HS-WEDM: new constant tension structure, float wire positioning limit, fuzzy controlled interval servo system and CAD/CAM automatic programming system with processing date base. The application of the 4 technologies show their advantages. 
