A Framework of Intelligent Remanufacturing System Based on Robotic Arc Welding

Remanufacturing Engineering has become a research focus and been receiving growing attention. With the development of manufacturing industry, parts are becoming more and more complex and precision. However, traditional remanufacturing method cannot always meet requirements. The authors propose an intelligent remanufacturing system based on the “modeling-slicing-stacking” principle. First, establish a 3D model by structured light scanner; then, acquire the layers information by direct STL slicing; and finally, select the optimum tool path plan and welding parameters. Taking a half cylinder shell as a worn part, this paper proposes L25 (56) orthogonal experiments to select the optimum path and welding parameters. Results show that the remanufacturing surface smoothness mean error is less than 0.5mm under the selected optimum parameters.
