Spatial curved surface with NC-WEDM-HS

In order to raise the productivity and precision of numeric control-wire cut electrical discharge machining with high speed (NC-WEDM-HS) system of multi-axes, the CAD/CAPP system of machining spatial curved surface with NC-WEDM-HS were established by programming in this paper. The characteristics and general laws of cutting complex curved surface by NC-WEDM-HS system of multi-axe were systematically analyzed, and then the motion parameters and motion forms of NC-WEDM-HS system of multi-axe were analyzed. The universal mathematical models of NC-WEDM-HS system of five-axes were derived. Good simulation results and CAD drawings were obtained. The application of the CAD/CAPP technology is illustrated with machining example. The simulation analysis and experimental results show that the efficiency of machining complex curved surface can be increased remarkably by application of this CAD/CAPP technique. All these works provide an effective approach to the problems of cutting complex curved surface parts by NC-WEDM-HS.
