| This task is a part of "Research on Total Quality Management System Based on Integrated Quality Information Technologies", supported by the National Natural Science Foundation of China.First, we introduced the development of exchange technology of product data and the appearance, content, realization, realization of STEP(Standard for the Exchange of Product Model Data). Meanwhile, the modeling language EXPRESS of product data of STEP is systematic introduced in this text. We researched data type, manifesto , expression of EXPRESS in detail.On the basis of the systematic introduction, we proposed CAD/CAPP/CAM quality information integrated system on the basis of the STEP.At new eras and enterprise produce the transformation of the management mode keen competition pressure, the change of the quality information processing work of the enterprise of our country has been already very urgent. Under this condition, on the basis of STEP standard, which has been apply widely, we proposed CAD/CAPP/CAM quality information integrated system. It has relatively high scientific value and value of practice to the quality information processing work level of the enterprise of our country and quality management level of the whole enterprise. |
