On world market, although mechanical manufacturing industry of Germany did not hold the most favorable position, but the core competition ability that it can weigh to going up is German economy however. The advantage of German machinery manufacturing industry is based on outstanding project and manufacturing technology not only, still depend on can the effective demand of basis factory, offer the skill that they require to build the best plant on the world ceaselessly. The factory is a complex and abiding product. Look from the angle of systematic project, the factory passes input parameter transition, production gives the product of high additional cost, realize rise in value thereby. Accordingly, the factory serves as " society - technology " the system is should OK undertake optimizing. With the development process likeness of complex product, we should be systimatic and systematization ground applies modern project tool to undertake plan ceaselessly and be improvemented continuously to the factory. The article introduces a referenced model, description but the program tool of compositive factory and process and its application limits. The factory is a product is in odd a small lot production is medium, because product, scale of production, technology and manufacturing task are in,change ceaselessly, the factory is in the environment of trends and acuteness change operation, must improve factory and process continuously, try to adjust at any time. If do not undertake necessary adjustment, reduce with respect to what can bring about factory resource to use efficiency. In other words, when production only the system maintains in enough tall flexible fall with the circumstance that gets used to ability, ability lives in dynamic environment. CNC MillingCNC Machining
