文章依据参数化特征建模技术论述了数控镗（铣）床ＴＫ６４１０ 主轴箱中几种关键零件三维实体的造型设计方法。对阵列、齿轮、零件族、零件族表等造型方式进行了较为深入的研究，此类方法正是产品建模系统强大的造型功能的具体体现。从而使系统具有方便快捷，自动化程度高、可扩充的功能。 Based on the parametric feature modeling technology, this paper discusses the modeling design method of three-dimensional solid parts of several key parts in TK6410 headstock of CNC boring (milling) bed. The research on the modeling methods such as array, gear, part family, part family table and so on has been conducted in-depth study. Such methods are the concrete manifestation of the powerful modeling function of the product modeling system. So that the system has a convenient, highly automated, scalable functionality.
