带角圆的回转铣刀上的等导程螺旋刃口研究

On spiral cutting edge with equal screw pitch with the toroidal revolving

先给出了任一回转铣刀上设计等导程螺旋刃口的通用模型，进而运用这一通用模型推导出锥状带角圆铣刀上连结刃口曲线方程，并用同样方法给出了柱状和以凸圆弧为母线的带角圆的回转铣刀上的刃口曲线，并介绍了其ＮＣ加工相关问题的研究方法，为同类研究提供参考。

First, the author gives common model for the spiral cutting edge with equal screw pitch on an arbitary revolving cutter. And with the model, the author derives the cutting edge curve equation on the totoidal coned revolving cutter. Later, the author gives the equations on the toroidal columned revolving cutter and the toroidal revolving cutter with the convex curve generatrix. At the same time, the author introduces the correlatives research methods on NC machining so as to provide valuable references for the further research.
