摘　　要：以弧面分度凸轮的几何学理论为基础,基于VB 6.0和Pro/E实现了弧面分度凸轮的三维参数化实体建模。通过VB编程语言,设计出能计算参数化的弧面分度凸轮理论廓面数据的友好界面。通过对凸轮基本参数的输入和运动规律的选择后,即可计算出相应的凸轮廓面坐标点,并将廓面数据保存为".ibl"格式。导入Pro/E 3.0中生成曲线,再生成曲面,然后将曲面合并,最后对理论轮廓曲面进行法向偏置、实体切除操作,获得与凸轮毛坯进行布尔相减运算后得到的凸轮实体模型。On the basis of geometric theory of globoidal indexing cam,the 3D parametric modeling of globoidal indexing cam is realized based on VB 6.0 and Pro/E. The friendly interface which can calculate the contour surface data of parametric globodial indexing cam is designed through the VB programming language.This interface can be used to calculate the value of the relevant contour surface points through basic parameters input of cam and the choosing of motion law of cam follower,and it will save the file as the format of ＂.ibl＂.After that,the file is imported into Pro/E 3.0 to generate curve and then the curves are merged into surface.At last,the normal offset and solid resection operation of theoretical contour surface are carried out,and the cam solid model after cam blank Boolean substracting operation is obtained.
