摘要
利用光内送粉技术，基于法向分层的路径规划，结合层高测量系统，对不等高扇形结构件的激光熔覆成形实现了闭环控制。提出了一种分层分段控制的新方法，使成形件宽度一致。建立了速度比例-积分(PI)控制器，使实际总堆高达到了期望值，实现了结构件的高精度成形。
Abstract
Based on the inside-laser powder feeding technology,the normal stratified path planning, and the high-level measurement system, the closed-loop control of laser cladding forming of fan-shaped unequal-height parts is conducted. A new method of hierarchical and segmented control is proposed, which ensures the width of forming parts consistency. The speed proportion-integration (PI) controller is established, which ensures that the actual heap reaches the desired value, and the high precision forming of structural parts is realized.
