| 摘 要： | 分析了当前零件库设计方法存在难以动态扩充的问题,提出了模型参数驱动的零部件设计方法;以注塑模具零件为例分析了零件参数的复杂性,提出以"单遗传结构"的形式描述零件参数,以多级别数据存储结构作为零件参数的存储方式,使得平面二维表格(或者复杂的树状表格)简化为线性数据结构,每条记录均成为仅包含参数控制关系的单个参数的数据,从而建立起可动态扩充的系列化、标准化的零部件库。利用这种建库方法,同时实现了三维零部件的离线式编辑。

A New Parts Library Design Method Driven by Model Parameters |
| |
| Abstract: | The difficult problem of how to expand the parts library dynamically is analyzed.Model parameters-driven part design method is proposed.Taking the injection mold parts as an example,the parts parameters′ complexity is analyzed.The single inheritance structure method is proposed to describe the parts parameters,and the multilevel data storage structure is proposed as the way to store the parts parameters,so that the 2D table(or complicated tree-like table) is simplified as a linear data structure.Each record of this data structure contains only one parameter for the parameter control relation.In such a way,the serial and standard part library is constructed which can be expanded dynamically.With this part library construction method,offline edit function of the 3D parts is realized. |
