用CAD方法实现铸造砂芯设计

Computer Aided Design on Foundry Core

根据组合机床中大型铸铁件的特点，首先提出了砂芯分类及设计原则，开发了砂芯设计程序模块，通过人机对话．自动生成砂芯工艺图。

Basted on the featrues of modular machine tool's iron castings, the rules of classification and design of core are proposed firstly, and tile program on core desing has been developed. This program can create core figure autommatically by man-machine dialogue.
