With the aim of improving the quality and efficiency of laser cladding remanufacturing of failed hydraulic cylinder piston rods,a remanufacturing process method combining inverse data acquisition and laser cladding path planning is proposed.Firstly,through the analysis of the failure form of the piston rod,the failure area model was obtained by using 3D scanning data acquisition,point cloud processing and data reversal;then,the laser cladding remanufacturing process was finally obtained by planning the laser cladding path and setting the process parameters.The results show that the method can effectively remanufacture the piston rod,with technical,economic and environmental feasibility,and the process can meet or even outperform the technical requirements of the original product.
