摘　　要：简要介绍Catia二次开发常用的几种方式。以渐开线齿轮形成原理为理论基础,采用Visual Basic(VB)对Catia进行二次开发,实现渐开线齿轮的高精度建模。目前,在Catia中建立齿轮三维模型多采用建立点、直线段连接的方法绘制齿廓线,这种绘制方法的误差不可知。直线拟合渐开线的自适应过程使误差可知并可控。运用VB完成直线拟合渐开线齿廓的自适应过程,判断在输入不同参数时建立点的数量,启动Caita并调用Catia绘图命令完成渐开线齿轮的参数化建模。给出了高精度齿轮建模的代码,使读者能够更好的理解Catia二次开发。Brief introduces Catia secondary development commonly uses several ways. Based on the theory of involute gear forming principle, the use of Visual Basic （VB） was carried out on the Catia secondary development to realize the high precision modeling of involute gears. At present, the method of building gear three-dimensional model in Catia/s often used to establish point and create straight line to draw tooth profile line. The error of the drawing method is unknown. The adaptive process of linear fittiag of involute let the error become knowable and controllable. Uses VB to complete the adaptive process of linear fitting of involute tooth profile, judging in different input parameters should establish number of point. Starts Caita and calls the Catia drawing command to complete parametric modeling of involute gear. High precision gear modeling code is given, and enables readers to better understand the Catia secondary develooment.
