基于实例的齿轮滚刀三维CAD模型设计

Case-based 3D CAD Model Design for Gear Hob

针对齿轮滚刀的设计特点,通过建立一个实例齿轮滚刀的三维CAD模型,将模型中的特征控制属性值定义为参数,并用高级语言开发齿轮滚刀参数计算和与三维CAD软件联接的应用程序。在应用程序中,实现齿轮滚刀参数的自动计算与齿轮滚刀三维CAD模型的自动修改,以达到齿轮滚刀的三维CAD模型设计自动化。

On account of the design feature of gear hob,this paper proposes to define the value of feature control property as the parameter by a case-based gear hob 3D CAD model,and then with advanced language an application program joined with 3D CAD software is designed.Designed to automatically generate the 3D CAD model of gear hob,this application can automatically calculate the gear hob parameter and modify 3D CAD model.
