Using the uniform information channels and the technology of SOAP and COM/DCOM/COM+, information integration among tool management system, ERP/MRPII, CAM and CAPP system is come true. Finally, the distributed tool management system is developed in using mutil-tired Client/Server model as the frame of software. It has the functions of tool general management, searching milling cutting data for CAM by providing the milling cutting data e-book and computer aided tool selection for CAPP by using expert system. The tool management system offers the tool-coding function, too. The study of tool management system in DNC improves the level of tool management and the flexible of arranging production, haleness and the automatic extent of DNC systems.
