2. This paper describes the tooth forms of an external toothing and chamfering gear shaping cutter and chamfering gear shaper cutters designed by old routine. 描述了外啮合修缘插齿刀和修缘齿轮的齿形，分析了按常规设计修缘插齿刀存在的问题。
3. The design of an internal toothing gear shaping cutter can be summed up to a multi-target optimization problem. A mathematic model for optimization is established. 把内齿轮插齿刀的设计归结为一个多目标的优化问题，建立了优化的数学模型。
4. This paper proposes an optimization method on the plate shaving cutter, its optimal solution is the premises matching the smallest toothing Angle on the condition of the last cutting grinding. 本文提出了一种盘形剃齿刀的优化设计方法，其最优解是最后一次刃磨时的最小啮合角对应的条件；刀具寿命期间，保证进入双齿啮合剃齿。
