A Study on Generation of the Advanced Laser Scanning Path for Stereolithography using Voronoi Diagrams

Voronoi Diagram 을 이용한 Stereo;ithography 의 향상된 레이져 주사경로 생성에 관한 연구

Voronoi diagrams are applied in varios field such as NC toolpath generation, VLSI design and robot path planning because of their geometric charcteristics. In this paper, Voronoi diagrams are introduced on polygon constructed by line segments only and with constant offset. Bisector curves for two arbitrary objects, which is the combination of line segment and arc, are defined as parametric fuction where the parameter is used as offset. Offset curves are applied on the generation of laser scanning path for the stereolithography and shows a good result from several examples.
