摘　　要：针对模具制造业中对数控加工复杂曲面的铣刀的需求越来越多的问题,设计了一种刀具端部为旋转抛物面的新型铣刀,建立了旋转抛物面型铣刀的等螺旋角切削刃曲线模型和正交螺旋形切削刃曲线模型,对所建立的切削刃曲线模型进行数值仿真,并通过SAACKE UWIF CNC刀具磨削中心制备出了旋转抛物面型铣刀,验证了旋转抛物面型铣刀切削刃曲线模型的正确性、旋转抛物面型铣刀设计及制造的可行性.A new kind of rotational paraboloid end mill is proposed for the machining of sculptured surfaces in mould industry. Then,the mathematical models of continuous cutting edge curve with constant helix angle and the orthogonal spiral cutting edge of rotational paraboloid end mill is presented. Then,all curves are simulated based on MATLAB software. Finally,the rotational paraboloid end mill is manufactured using a SAACKE UWIF CNC grinding machine. The validity of the mathematical models and the feasibility of rotational paraboloid end mill are verified.
