CAPP环境下机床选择模块的设计方法

The Design Method of Program Module for Selecting Machine Tools Under CAPP Enviornment

所提出的机床选择模块是重型机械零件ＣＡＰＰ环境下的一个主要功能模块，它以黑匣子原理设计接口程序，对数据库进行操作，选出机床．其中的机床选择方法引进了多目标离散变量的优化设计技术，以期达到最佳利用机床设备的效果，该模块由数据库支持，其覆盖面广、操作速度快，对操作内容的维护极其方便．

The machine tools selecting program module put forward in this paper is a main func-tion module under heavy-duty machin part CAPP enviornment.On the base of the“dark box”principle,the interface program was designs,operates the datebase was operate and machinetool.were chosen at last.In the machine tools selecting process the optimal design techniqueof multiobject discrete variables was used in order to get the effect of optimum use of the ma-chine tools.This module is supported by database covering a wide field,having a highoperating speed and the can be easily maintained.
