Abstract
Network-based Manufacturing (NM) is one of the main development trends of modern
manufacturing industry. Computer Aided Process Planning (CAPP) is serving as the
important NM-enable technology. Its characteristics work and collaboration are the
key factors of essful implementation of CAPP in NM. Some key technologies of
collaborative process planning work-based Manufacturing (NM-COCAPP) are
studied.
Firstly, the demands of NM-COCAPP are analyzed. Then a framework of
NM-COCAPP that consists of browser, application server and database server is built.
Some fundamental technologies involved are introduced.
Then the technology of collaboration in NM-COCAPP is researched. The
characteristics of collaborative process planning are analyzed. The conception and
connotation of collaborative process planning are proposed. Then a collaborative design
model for process planning in NM is built. Some issues involved, such as process planning
task solving, management and control of process planning flow, are discussed in detail. The
modeling and integration of manufacturing resource are studied. A manufacturing resource
model based on XML is presented.
Thirdly, pr
