Path Planning of Arc Additive Remanufacturing for Defective Castings

Abstract

According to the characteristics of weld lap and weld layer accumulation in remanufacturing process, the path planning algorithm is studied, and a compound scanning algorithm is proposed to meet the requirements of complete filling and smooth surface in remanufacturing area. The remanufacturing path planning tool is developed by UG secondary development platform, and the path planning result is obtained by importing point cloud data. The robot welding workstation is used to experiment the planning results, and the original shape of the defective mold is basically restored after the experiment, which verifies the correctness of the planning results.
