激光沉积制造成形表面偏差监测与反馈控制
Surface deviation monitoring and feedback control of laser deposition manufacturing
摘要
Abstract
To address the issue of concave and convex deviations on the surface of laser deposition manufacturing,an algorithm for surface deviation monitoring and feedback control was designed.Surface deviation monitoring was achieved through three-dimensional point cloud reconstruction,coordinate system registration,simplified noise reduction,and deviation value calculation.The feedback control algorithm extracted contour profiles of deviation zones,generating layered compensation trajectories for concave areas and zoned control trajectories for convex areas,thereby implementing feedback control over surface deviation regions.A validation experiment was conducted:the surface deviation monitoring and feedback control programe promptly identified concave and convex deviation zones on the test specimen surface and applied feedback control,significantly reducing surface flatness errors.This demonstrated the effectiveness of the forming surface deviation monitoring and feedback control algorithm,holding significant implications for the advancement of laser additive manufacturing technology.关键词
