Geometric Tolerancing: Theory, Issues and Computation
Geometric Tolerancing (GT) is a cornerstone of manufacturing
sciences and engineering. Much work has been done in
the specification language and semantics of GT, especially at the
level of professional standardization (ISO, ASME-ANSI, etc). Somewhat
more recent is the interest in metrological issues and computation.
We outline some basic elements
of a mathematical theory of GT, which may shed some light
on the current professional standardization activitivies.
We also describe some new computational approaches to
GT metrology and computation.
