基于图解法的凸轮廓线CAD设计

Design of Convex Outline by Graphic Method Based on CAD

以AutoCAD2000软件为设计平台,基于凸轮廓线图解法(反转法)的设计原理,通过实例,介绍了用交互式作图设计凸轮廓线的方法。灵活运用各种绘图、编辑及辅助功能,对于不同从动件类型(平底、尖底、滚子),阐述了相应的作图技巧。该方法简单、实用,效率高,并能达到较高的设计精度。

This paper presents a method of designing outline of cam based on AutoCAD software. It follows the procedure of graphical treatment(turn over method),but adopts interactive graphical mode to get the outline of cam to be established. The drafting techniques are expounded for different kind of driven member(plat,point and roller bottom)by using flexibly every kind of function of drawing,editing and other assistance. This method is simple, practical and efficient, and can achieve higher accuracy of designing.
