本文在考虑齿面摆线运动、跳动和齿距不均匀的情况下，推导出了铣削切屑厚度的解析表达式。为了推广该方程，将与铣削相关的切削参数（线性进给、刀具转速和半径）组合成单个无量纲参数。新参数允许铣削过程的抽象，并允许在铣削中选择最大可能的切屑厚度。还建立了切削的入口角和出口角的方程。新模型给出的切屑厚度值与先前的模型进行了比较，并显示出较低的误差水平。
In this paper an analytic expression for chip thickness in milling was formulated while considering the cycloidal motion of the teeth, runout, and uneven teeth spacing. In order to generalize the equation, the cutting parameters associated with milling (linear feed, tool rotational speed, and radius) were combined into a single, non-dimensional parameter. The new parameter allowed abstraction of the milling process and enabled selection of the maximum possible chip thickness in milling. Equations for entry and exit angles of a cut were also developed. The chip thickness values given by the new model were compared to prior models and showed lower error levels.
