本文叙述了用于加工线性螺旋面零件的盘形和指形刀具齿形的计算方法。这种方法基于这类螺旋面——端截面内为延长(缩短)渐开线的螺旋面以及渐开线和阿基米德螺旋面——有着共同的构成原理,因而有可能将加工这些螺旋面的刀具计算公式归纳为通式。只要代入各种不同螺旋面的特性参数,便可求出相应的刀具齿形。——编者 This article describes a method for calculating the profile of disk and finger tools used to machine linear helical surfaces. This method has the common principle of composition based on the helical facets in this type of helicoid-end cross-section that extend (shorten) the involute and the involute and the Archimedean helicoid, so that it is possible to process these helices Surface of the tool calculation formula generalized. As long as the characteristics of the parameters into a variety of different helical surface, you can find the corresponding tool tooth shape. --editor
