摘　　要：以共轭齿面包络原理为理论基础,布尔运算为方法,商用三维实体软件为工具,研究了磨前滚刀加工圆柱齿轮的计算机虚拟加工问题,利用CATIAV5的二次开发功能构建出磨前滚刀加工圆柱齿轮的虚拟仿真加工系统。对仿真系统虚拟加工的齿轮齿廓进行了曲面重构,得到了精确齿轮实体模型,通过分析模型的公法线误差,验证了该方法的正确性。为基于包络制造原理的曲面零件的数字化制造提供了一种有效方法。Based on the gear generation principle, taking the Boolean calculation as the method and the commercial three dimensional software as the tool, the gear virtual manufacture system using the CATIA V5 secondary development function was constructed. Carrying on the curve fitting to the tooth profile of the virtual machining gear model, the accurate gear model was obtained. The validity of this method was validated through analyzing the common normal length error of the model. An effective method to establish accuracy gear three dimensional solid mold was supplied.
