Abstract:
According
to the characteristics of RP technique, a method of geometric modeling
for complex surfaces is proposed. The method is capable of constructing
the optimized STL file (the de facto file for RP machines) directly from
digitized part data, so it radically avoids mistakes arisen from
conversion by means of commercial CAD software systems. In addition to
realizing the perfect match of grid number and reconstruction tolerance,
the approach also improves the efficiency of RP pretreatment. Meanwhile,
it provides a reliable way for the organic integration between reverse
engineering RP technology.
Key words:
