摘　　要：在齿轮加工中渐开线轮廓加工精度将直接影响到齿轮的性能,论文提出了用AutoLISP语言绘制渐开线齿廓的方法,实现了渐开线轮廓的参数化设计,可以依据齿轮的精度要求来绘制相应的渐开线齿廓。然后在MasterCAM环境下进行了渐开线圆柱齿轮的数控加工仿真并生成了数控加工代码。实验结果证明,该方法提高了齿轮轮廓绘制以及数控加工的精度。使用该方法进应用于生产加工,可以改善齿轮的性能,同时也提高了生产效率。Precision of Machining of involute cylindrical gear will affect the gear＇ s performance directly. This article introduce a method of drawing involute gear contour using AutoLISP, it realizes gear＇ s parametric design, and we can draw involute gear contour according to gear＇ s accuracy specification. Then is uses MasterCAM software for simulating NC machining of involute cylindrical gear. Result of the experiment refers that, this method can improve precision of gear contour and NC machining. Applying in manufacture, it can improve performance of gear, while it can also improve efficiency of manufacture.
