文档介绍：摘要
本设计的主要内容是以知识库为基础,利用专家系统的推理功能,开发的可转位车刀选用专家系统。编程工具为Microsoft公司的Visual Basic ess。本系统的知识表示方法采用的是产生式规则,知识库主要表现为一张张规则表。系统主要用于实际生产中,帮助工人根据加工条件选择合理的可转位车刀片的材料和型号。所以系统具有界面美观友好的特性、不易崩溃的特性、输入很人性化、输出一目了然。系统有三大功能模块:用户验证管理模块、推理机模块、知识库模块。两种权限一般用户和管理员,具有管理员权限的用户能修改更新数据库里面的数据。用户验证和两种权限的设置一同构成了本系统的安全保障。经过2个月的努力,本系的核心功能有两个。其中一个是引导用户一步一步输入决策字段并选择合理的专家推荐结果,然后结合两者最终得出最合理的刀具材料和型号。另一个核心功能是具有管理员权限的用户管理系统的知识库,包括删除添加修改等操作。

Abstract
The main content is based on the design of knowledge-based and use of expert system inference to development indexable turning tools selected expert tools is Microsoft Corporation's Visual Basic and Office 2003, knowledge representation of this system is production rules。The main content of knowledge base is rule table。System is mainly used for actual production to help worker choose the right materials and models of indexable turning tools。Therefore, the system features has beautiful interface friendly,not crash characteristics,input is very user-friendly, output at a glance. System has three functional modules: user authentication and management module, inference engine module;knowledge base permissions:general users and administrator,A user with administrator privileges can modify and update the data of authentication and permissions to set the two together constitute the security of the system. After 2 months of hard work, the Department has two core functions. One is to guide the user step by step, making the input field and select a reasonable e of mendation,bine both to work out the most reasonable tool material and model
. Another core feature is a user with administrator privileges can management the knowledge base of system, including the deletion of add, modify and other operations.

1前言
puter-Aided)化极大的提高了生产效率,但是刀具选用还比较欠缺计算机的帮助。目前在工厂实际生产中,工人一般凭借个人的经验来选择可转位车刀片,而由于可转位车刀片的材料、型号繁多的客观原因。使得工人很难选择
