The source and composing of process planning knowledge is analyzed based on the state of art in discrete mechanical manufacturing enterprise. On the basis of the widely application of computer aided process planning system (CAPP) in mechanical manufacturing enterprise, the concept of process planning knowledge discovery (PPKD) is proposed for product process planning database. CAPPFramework (a CAPP development platform that is developed by Northwestern Polytechnical University supported by China) is taken as a basic development platform, the technology architecture of process planning knowledge discovery is founded based on object-oriented model driven technology, and the process planning knowledge discovery script is designed. Elementary application research in typical process summarization is described in detail. The technology of PPKD has been used in mechanical manufacturing enterprise to support the automatically knowledge acquisition in CAPP system, and it shows good application effect.
[Show abstract][Hide abstract] ABSTRACT: Procedures are a common knowledge form in process industries such as refineries. A typical refinery captures hundreds of procedures
documenting actions that operators must follow. Maintaining the action-knowledge contained in these procedures is important
because it represents a key organizational asset that can be leveraged to minimize the threat of accidents. We develop an
approach that extracts services from these operator procedures. The paper describes the heuristics underlying this approach,
illustrates its application, and discusses implications.
