This work defines an expert machinability data system integrated with a CAD
system, for computing complete machining parameters required for further processing
with NC software. The main objective is to move toward the concept of a fully
computerized system, from design to the generation of NC code which can be directly
sent to a manufacturing unit. A typical example of such a system, MICADEX, is described
in this thesis. MICADEX is capable of retrieving geometric description of
components from their 2-D CADAM drawings using the IUE (CADAM Access) facilities
and making decisions on machining parameters required for the turning operation, in
consultation with the user. MICADEX is designed to be a representative example of
an intelligent system capable of providing virtual machining facilities on a CAD system,
and lt does not require its users to have a high level of engineering skills.
