A new type of IMNC for box-shaped parts has been developed which can achieve various intelligent processing functions such as automatic adjustment of the part's roughlocalization;blank remainder based automatic determination of cutting times in rough machining;quality control supervision, measurement and machining compensation in fine processing, and breakdown anticipation in drilling,reaming and tapping. The IMNC is integrated with the CAD/CAPP/CAM environment and can be automatically generated on the CAM console. The flexibility of the manufacturing system's facilities layer has been greatly improved.展开更多

Amodule definition modelfor modular design and manufacturing of heavy duty NC machine tools isbulit and the essential composition of the module definition model (MDM) is discussed in detail. Itis composed of two models: the part definition model (PDM) and the module assembly model(MAM). The PDM and MAM are built and their structures are given. Using object-oriented know-ledge representation and based on these models, an intelligent support system of modular design forheavy duty NC machine tools is developed and implemented This system has been applied to thepractical use of Wuhan Heavy Duty Machine Tool Works展开更多
