強力刮齒法是以Wilhelm von Pittler 於 1910 年所提出的專利為基礎所開發的一種加工方式。這種切齒方法可以用來加工內齒或外齒之圓柱齒輪，尤其適合加工內齒輪，且生產效率要高於滾齒和插齒。特別在減速機中，內齒輪的應用愈來愈多，也使得內齒輪的加工的需求愈來愈高。
因此，本研究的目的主要是利用曲面共軛理論及齊次座標轉換矩陣，對強力刮齒法刀具進行數學模；並根據 ISO 所定義的參考平面，分析刀具各種切削角度；除了解刀具幾何特性外，並可依此修正強力刮齒刀具的設計參數，以避免出現負的間隙角。最後，利用 DEFORM 對所設計出的刀具進行切削模擬。

Power skiving is a processing method develop based on Wilhelm von Pittler’s patent, which was introduced in 1910, this type of gear cutting method usually used on internal and external gear of cylinder gear, especially fit for internal gear processing, and it’s production efficacy needs to be higher than hobbing and shaping, we can see more and more application, particularly on reduction gear.
This Study mainly focus on design a conjunction surface theory-based power skiving tool. We first use homogenous coordinate conversion to obtain the coordinate of gear, tool, virtual conjunction surface and rake face, by doing so we can obtain the cutting edge. Then we can redesign the Power skiving tool by using reference plane defined by ISO, to certify each tools perspective, and avoid negative working clearance angle, then use the profile shift to construct a complete model of power skiving, and use DEFORM to simulate the cutting process
