| Abstract: | Based on the principle of layered-carving and accumulative-forming, the principle and techniques of 3D laser carving are introduced. In view of the scanning efficiency and performance of scanning system, beeline scanning is selected as the scanning mode. The principle of beeline scanning is described and the algorithm of creating scanning line for cavo-relievo and relievo is given. When islands exist within an outer loop, an approach of continuous scanning to avoid intermittent working of laser is presented. The application results show that this scanning algorithm is reliable and efficient and completely meets the requirements of 3D laser carving. |
