Process information transferring for cutting paths in laser manufacturing

In laser manufacturing, the cutting parameters, such as power, speed, assist gas pressure, and stand off distance, have a great influence on quality of machined parts. To ensure part, process information (cutting parameters) needs to be manually assigned adjusted according different geometry characters part edges, like arc line segment. The contours are then used for generating paths, leaving behind. Quickly accurately transferring corresponding paths is not an easy task. this paper, algorithm proposed passes by points in paths. First, all edges containing offset generate closed contours. Then, whether included judged marked. Finally, NC codes through adjacent outputted. simplify computation work, fast approach also determine point cloud contained contour. feasibility computational efficiency algorithms verified examples, actual comparison verifies superiority details
