| Abstract: | An algorithm of closed 2D point-sequence curve offset reconstruction was studied for rapid prototyping data processing. Basic principles and characteristics of several existing algorithms on offset boundary reconstruction were analyzed. The peculiarities of the closed PS curve offset in rapid prototyping data processing and the rule of intersection point generation were analyzed. A new algorithm for offset boundary reconstruction was proposed, which was based on the valid intersection points searching. The algorithm had been compiled in the developed RPM data processing software. Using the new algorithm, the stability is improved and the OFFSET tool path can be generated in the RPM process. |
