Abstract:
Three types of modeling and simulation technology in digital
manufacturing are analyzed, i.e. product modeling and simulation
technology, process modeling and simulation technology, manufacturing
system modeling and simulation technology. Based on some research
projects, digital product modeling technology oriented to manufacturing,
numerical control pipe bend process modeling and simulation technology,
virtual assembly and assembly process simulation technology, production
line modeling and simulation technology are discussed emphatically. A
conclusion is pointed out that process modeling and simulation
technology, including product’s machining process, assembly process,
production system planning, reorganization and simulation technology is
very important to improve manufacturing system’s efficiency and
reliability, realize the optimization of production resource and
machining process, transfer mode from traditional manufacturing to
foreseeable manufacturing. At last, some key techniques which enhance
digital modeling and simulation technology’s practicability are listed.
