马春晖, 同淑荣, 李靖. Classifi cation and Hierarchical Model of Manufacturing Knowledge Supporting Process Planning[J]. Aeronautical Manufacturing Technology, 2011, 54(18): 86-88.
The aim of this research is to classify and model manufacturing knowledge required by process planning. The relationship between manufacturing knowledge and process planning is analyzed. According to roles of manufacturing knowledge in process planning
manufacturing knowledge is categorized into three classes which are manufacturing resource class
artifact class and manufacturing process class. A hierarchical model of manufacturing knowledge is constructed that is consisted of part level
attribute level and database level. Taking manufacturing equipment as a case
an expressive model of manufacturing knowledge is set up by using IDEF1X method.
