The Manufacturing Advisory
Service (MAS) is a concept level manufacturing process and material
selection tool. The MAS generates a dialogue with the designer,
inquiring about batch size, typical tolerances, size, overall shape,
and cost requirements. At each step along the way, the user is presented
with an updated, ranked list of manufacturing possibilities. A similar
method is used to define the attributes for material selection (yield
strength, density, etc.), and generate material rankings. The final
result is a ranked list of viable combinations, obtained through
a process/material pair optimization.
The MAS is a Java(TM)
applet freely available via the world wide web. It is inter-linked
with web pages of tutorials, and reference pages explaining the
facets, fabrication processes and material choices. The MAS performs
its calculations using capability data from a remote database -
which can be maintained and updated via the Internet. A framework
is provided for a first order cost estimation - along with examples
for selected processes. Another extension provides for the generation
of process chains - using secondary processes to refine certain
features on a part.
