3.3.2. Benefits of CAD/CAM
CAD/CAM integration is certainly unavoidable for production companies for
their innumerable benefits. Warman cites the six primary benefits arising from
the use of computer integrated technology as follows:
1) More accurate drawings: the accurate geometry provided
by CAD systems means that the checking of drawings and the
production of various dimensions is greatly simplified. This,
coupled with the use of layering technique, enables assembly
or tolerancing problems to be addressed.
2) Redrawing eliminated: component drawing often occurs in
non-CAD environment. Operations such as jig and tool design,
manufacturing planning and parts catalogues can all make use
of the single accurate geometry held within the CAD system.
3) Rapid changes and updates: the production of new
components based on the existing ones is very fast and
alterations can be rapidly implemented and checked. In many
organizations, the main activity is the reshaping of existing
designs rather than producing new ones.
4) Variety reduction: using a CAD system and a good parts
classification system, it is simpler to extract existing drawings
to determine if old parts can be used within new products.
5) Parametric design: CAD provides the opportunity to
describe components by parametric dimensions, so by
inputting actual values, new components can be quickly
produced.
6) Faster drawing production: this aspect is generally treated
as the key factor in any justification of a CAD system. Various
