The consideration of manufacturing objectives at the design
stage is a real possibility given the recent availability of
solid modellers within Computer Aided Design (CAD) systems.
However, designers and engineers can experience difficulty in
communicating with these CAD systems because of the
mathematical language which is often used. The ability to
capture and transfer design information pertinent to
manufacture is also generally rather limited.
This thesis describes the development of a language that uses
familiar engineering terminology to specify solid models of
engineering components. The descriptive nature of the
language naturally incorporates information useful to
'downstream' manufacturing functions; an example of process
planning for turning is included.
In order to test the principles proposed a questionnaire was
administered to fifty experienced engineers from a wide range
of disciplines. The findings of this questionnaire are
