The primary coverage as follows:Firstly, according to the running features of the globoidal indexing cam mechanism establishes mathematical model, then builds overall design.
主要内容如下：首先根据弧面分度凸轮机构的运行特点建立数学模型，并进行总体设计。

Since the profile of the globoidal indexing cam is a spiral surface, traditional machining technology couldn't meet it's accuracy demands.
弧面分度凸轮轮廓面为一空间不可展开螺旋面，传统的加工工艺很难满足其精度要求。
