I looked for this kind of capability at Autofact '97. Some programs you
to look into:
Delcam's CopyMill/CopyCad programs
Cimitron's CAM systems
Tebis AG's Tebis 3.0
In my opinion all have good capabilities for importing, and machining
models like STL or DXF files. They generally offer a variety of cutting
so that surface finish and machining time can be traded off as
Additionally some major CAM systems do 3axis machining from a facetted
model, but may
not be able to directly import a facetted model.
Hymarc makes a scanner, whose data can be easily polygonized. This
offers our customers
a route to CNC tooling that avoids the 'classic' surface reconstruction
step (thus my
interest in the subject).
