摘要
凸轮轮廓线的设计利用图解时设计精度很低，解析法也要经过多次反复计算才能得到满意的设计结果，手工设计计算量大，而且效率很低．论文介绍了一套简单实用的凸轮轮廊线ＣＡＤ软件系统，从而可以快速精确地进行设计．
The design precision of cam outline is very low by graph.Usually with analysis the satisfactory design result can be gained by calculating time and again.The calculation for making design by hand will take a long time and effciency is very low.This paper introduces a simple and practical CAD software system of cam outline,Which can carry on the design quickly and accurately.
