本课程设计以尖顶从动件偏心盘状凸轮机构为例，基于Visual Basic软件编写凸轮轮廓计算机辅助设计程序，实现了既能可视地展示机构的运动，又能给出凸轮轮廓上各点所对应的极角和极径，实现计算机辅助设计。-This course is designed to spire discoid eccentric cam follower, for example, based on the Visual Basic software development, computer-aided design program cam to realize both visual display of body movement, but also the various points on the cam profile is given by the corresponding polar angle and polar diameter to realize computer-aided design.
