Power-skiving is one of the most effective methods for manufacturing high-accuracy gears, especially internal gears. However, the machining accuracy of the gear is fundamentally dependent on the design accuracy of the tool. Due to their particularity, the design of power-skiving tools is complex and computationally intensive, and requires particular attention to the problem of interference. Solving the interference problem involves two main considerations, namely avoiding interference between the clearance surface of the tool or the tool itself and the original designed gear surface and preventing a zero or negative clearance angle. Both interference situations are particularly prone to occur in internal gear cutting. Accordingly, the present study proposes a new power-skiving design and full-view angle analysis method for the design of high-accuracy and simple cylindrical power-skiving tools which avoid both interference scenarios. The results obtained for a typical illustrative example confirm that the proposed method provides an uncomplicated and robust approach for modeling the design features of power-skiving tools.

动力交换是制造高精度齿轮，尤其是内齿轮的最有效方法之一。但是，齿轮的加工精度从根本上取决于刀具的设计精度。由于其特殊性，电动工具的设计复杂且计算量大，需要特别注意干扰问题。解决干涉问题涉及两个主要考虑因素，即避免刀具的游隙表面或刀具本身与原始设计的齿轮表面之间的干涉，并避免零或负的游隙角。在内齿轮切削中，两种干扰情况都特别容易发生。因此，本研究为避免上述两种干扰情况的高精度和简单圆柱型电动剃刀的设计提出了一种新的电动剃刀设计和全视角分析方法。针对典型说明性示例获得的结果证实，所提出的方法提供了一种简单而健壮的方法来对电动工具的设计特征进行建模。
