Abstract：To improve the manufacturing efficiency of stream turbine blade and shorten the productionperiod of stream turbine,a new method for the envelope milling of curved surface of stream turbine bladewith the circular disc cutter was proposed through analyzing the surface configuration and processing methods of stream turbine blade.With the minimal orientation-distance principle,the cutter-contact point and tool path of circular disc cutter in the envelop milling were calculated,and the calculation model and method of cutter-contact point were studied.After adopting the proposed method,the tool path length is significantly shortened than that with adopting the ball-end cutter envelope machining.And the proposed method has an obvious effect on improving the machining efficiency of blade.The present research can provide the theoretical references for the design of specific computerized numerical control (CNC)machine tool and blade polishing machine.
