研究目的
Development of an in-situ laser machining system integrating laser measurement and machining using a 3D galvanometer scanner.
研究成果
The in-situ 3D laser machining system successfully integrates measurement and machining, offering technical and cost advantages over conventional methods. It simplifies the operation process and reduces labor and time costs, with potential for higher precision applications with more precise vision devices.
研究不足
The error increases with the distance from the origin of the world coordinate system due to inaccurate camera parameter calibration. The height calibration method's error is stable but limited by the line structured light's thickness and camera resolution.
1：Experimental Design and Method Selection:
The study built an in-situ 3D laser machining system using a 3D galvanometer scanner and an industrial camera. A line structured light measurement model based on the galvanometer scanner was proposed.
2：Sample Selection and Data Sources:
A standard-height step block and other workpieces were used for measurement accuracy tests and in-situ machining verification.
3：List of Experimental Equipment and Materials:
A 3D galvanometer scanner (SCANLAB intelliSCANse 14), an industrial camera (Vieworks VH-5MG), and a 1064 ns fiber laser (RFL-P30Q) were used.
4：Experimental Procedures and Operational Workflow:
The process included pre-calibration, in-situ 3D measurement, machining pattern projection, and in-situ 3D machining.
5：Data Analysis Methods:
The optical center was extracted using the gray centroid method, and 3D point clouds were generated for analysis.
