用单角铣刀(一刀成)加工圆柱螺旋刃铣刀的周齿,将前面、齿背及刃带同时加工成形。其加工方式为:用铣刀的刀尖挑出工件的前刃面;用铣刀的锥面(角度刃)加工工件的齿背及刃带。对于加工前刃面的计算,是根据已知的刀具旋转面求工件的螺旋面,即旋转面作螺旋运动时曲面族的包络。加工齿背及刃带的计算,是根据已知的工件螺旋面求刀具的旋转面,即螺旋面作旋转运动时曲面族的包络。用干涉法(单角铣刀法)加工螺旋前刃面的计算在资料中已有介绍,但参考资料中的计算是在将单角
With a single-angle milling cutter (one knife into a) processing of cylindrical helical cutter edge, the front, back and ground at the same time processing and forming. The processing method is: pick out the front edge of the workpiece with the tip of the milling cutter; and use the cone of the milling cutter (angle edge) to process the back and edge of the workpiece. For the calculation of the blade surface before machining, the helical surface of the workpiece is obtained according to the known tool rotating surface, that is, the envelope of the surface family when the rotating surface makes helical motion. Machining tooth back and margin calculation, is based on the known work piece helical surface and the tool rotation surface, that is, when the helical surface rotation for the movement of the surface family envelope. The calculation of helical anterior rake surface by interferometry (single-angle milling cutter) is described in the literature, but the calculation in the reference is based on the assumption that the single angle
