摘　　要：针对绘图软件在绘制凸轮二维图的过程中所存在的周期长、效率低的问题,对AutoCAD软件的二次开发进行了相关研究。以盘形槽凸轮机构为例,运用Visual Studio2015开发工具,采用Visual C#语言对AutoCAD软件进行了二次开发,结合凸轮设计的原理,在Visual C#人机交互界面中输入了相关参数,完成了盘形槽凸轮的绘制,最后利用Solid Works软件对绘制出的以修正正弦为主运动曲线的盘形槽凸轮二维图进行了三维建模,以及运动仿真分析。研究结果表明:运用Visual C#对AutoCAD软件进行二次开发求取凸轮轮廓曲线的方法,能在够保证盘形槽凸轮轮廓曲线精度、缩短其绘图周期的前提下,实现盘型槽凸轮的参数化绘制。Aiming at the long cycle and low efficiency of drawing software in the process of drawing the two-dimensional map of the cam mechanism,the secondary development of Auto CAD software was related to the study. The disc groove cam mechanism was taken as an example and Visual Studio 2015 was used. Auto CAD was redeveloped by Visual C# language,combined with the principle of the cam design,the relevant Parameters were input in the Visual C# man-machine interface. The drawing of disc grooved cam has been completed. Finally,using Solid Works software,three-dimension modeling and motion simulation analysis of the two-dimensional map of disk grooved cam with the modified sinusoidal main motion curve were performed. The results indicate that the method of obtaining the cam profile curve by using Visual C# to perform secondary development of Auto CAD software is feasible,it can realize the parameterization of the disc groove cam under the premise of ensuring the accuracy of the cam profile curve of the disc groove and shortening the drawing cycle.
