Abstract: The key techniques of modular
design of heavy duty NC machine tools are described. A module
definition model for modular design and manufacturing of heavy
duty NC machine tools is built and the essential composition of
the module definition model (MDM) is discussed in detail. It is
composed of two model: the part definition model (MDM) is
composed of two models: the part definition model (PDM) and the
module assembly model (MAM). The PDM and MAM are built and their
structures are given. Using object-oriented knowledge
representation and based on these models, and intelligent
support system of modular design for heavy duty NC machine tools
is developed and implemented. This system has been applied to
the practical use of Wuhan Heavy Duty Machine Tool Works.
Key words:
Modular design Module definition
