摘　　要：为了实现对PCBN刀具多媒体信息的综合管理,以Visual Basic为平台,运用Visual Basic的数据库接口技术及Microsoft SQL Server 2000数据库管理系统,建立了PCBN刀具多媒体切削数据库,针对视频数据量较大的特点,提出了操作相对路径的方法,可使操作的数据量从几兆减少到几个字节.实践证明,此方法既满足了本数据库所要求的各种功能,又显著提高了系统的运行速度,实现了对PCBN刀具在各种加工条件中相关信息的综合管理.In order to manage the multimedia information of PCBN cutting tools synthetically,this database is developed on the platform of Visual Basic, at the same time, it also uses the connection technology of Visual Basic and the management system of Microsoft SQL Server 2000. It proposes the method of operating relative route to the great video data so as to reduce the operated data from several mega byte to several byte. It has been proved by practice that the method of operating relative route not only can realize various required functions of a data base smoothly but also improve the running speed of the system obviously and realize the management function to the relevant information of PCBN cutting tools in various processing condition.
