Abstract: Developing
CNC measuring method on the base of coordinate machine can make
the best of the hardware resource of CNC system
and realize the
integration of CAD/CAM/CAT. Based on the evenly spaced parallel
planes scanning, a new
adaptive digitizing approach for freeform surface namely arc
length extrapolation is put forward. By this way, the digitizing
approach can be added to the CNC system, while the system’s
hardware and software are not changed.
Key words: Reverse
engineering Freeform surface digitalization CNC non-contact
measurement Arc extension
