Research Of Extended Enterprise Networked CNC System

The manufacturing industry has been a motive power of the development of National Economy and backbone of Economic Development. With the fast development of Information Technology and dynamic variety of market, traditional environment of manufacturing industry has been under a fundamental change, and then a kind of advanced manufacturing mode called Networked Manufacturing came into being, and it can adapt to the society of information. Networked Extended Enterprise is a fantastic organization form to adapt to Networked Manufacturing. Networked Extended Enterprise makes use of the network technology, especially Internet technology to surmount the space obstacle between different enterprises, share knowledge and resources, and collaborate with each other in a serial of manufacturing activities such as Product Design, Production, Marketing, Procurement and Management. By doing this, Networked Extended Enterprise operates in an Environment of Collaborative Commerce, supplies product to meet the customer's requirement, and makes the design cycle of product become short, lower the cost, and eventually upgrade the core competence of the Industry chain.In the networked extended enterprise's environment, has brought the new opportunity and the challenge for the network numerical control, thus had the necessity applies the new knowledge, the new technical unceasingly perfect network numerical control theory and the technical system, enabled the network numerical control research to adapt the extended enterprise's environment.This article analyzes the present network numerical control system and the networked extended enterprise to the numerical control processing request, proposes based on gray relation grade theory numerical control equipment resources choise algorithm, optimizes extended enterprise numerical control resources sharing and disposition.This article in the correspondence data quantity major problem which the analysis at present in the network numerical control system in the real-time...
