中文摘要	Conventional NC programming cannot guarantee precise and real-time control of the relative position between the wire electrode and the workpiece when a 3-D curved surface is machined using a wire electrical discharge machine (WEDM). A CAD/CAM software was developed to calculate the wire electrode position and orientation at the machining point based on the CAD data of the machined surface to determine the machining point movement direction according to the cross product between the normal vector at the present machining point and the vector along the wire electrode axis with the NC commands then automatically generated to machine the 3-D curved surface. A spherical surface was machined using the software, with the finished spherical surface matching well with the design shape. The results also show that machining accuracies greatly depend on the discharge gap and the tangential feeding mode.
