采用盘形铣刀加工圆柱螺旋曲面，工件上的螺旋曲面是盘形刀具切削刃回转面螺旋运动所形成的包络，两个面在空间相对运动的任一瞬时必沿一条曲线相切，此曲线称为接触线。接触线缆工件轴心线作螺旋运动，便形成工件的螺旋曲面，绕刀具轴心线回转便形成刀具回转面。依照有关文献的解析法，建立了一套加工圆柱螺旋曲面用盘形铣刀廓形设计的向量法。经实例应用，表明向量法具有直观。简捷、形象、实用等优点，对无专用数控机床的中小型机械制造厂提高单螺杆式机械的制造质量，具有普遍实用性。
Cylindrical helical surface is machined by a disc cutter. The helical surface on the workpiece is the envelope formed by the helical movement of the rotating surface of the disc cutter. The two surfaces must be tangent to a curve at any moment of relative motion in space The curve is called the contact line. Contact the workpiece axis of the cable for helical movement, will form the workpiece spiral surface, around the tool axis rotation will form the rotary surface of the tool. According to the analytic method of the related literatures, a set of vector method for the profile design of disc cutter used for machining cylindrical spiral surface was established. The examples show that the vector method is intuitive. Simple, image, practical and other advantages, no special CNC machine tools for small and medium-sized machinery manufacturers to improve single screw machine manufacturing quality, with universal usability.
