Abstract：

In order to solve the problems of exact dimension difficult to control, welding material waste caused by large machining allowance, poor structure and property stability of hot forging mold and so on when the crankshaft forging mold was repaired by manual welding, the automatic wire arc additive remanufacturing technology was put forward replacing the traditional manual welding, and the low-cost advantage of a failed hot forging mold as a remanufacturing matrix and the precision advantage of automatic wire arc additive remanufacturing were fully realized. First, the process of automatic wire arc additive remanufacturing for the crankshaft forging mold was formulated, and the target model of wire arc additive filling part was obtained by the three-axis scanning and subsequent model processing of crankshaft forging mold to be repaired. Then, the layer-by-layer filling path planning was generated in self-developed path planning software, and the filling path was converted into a robot command file. Finally, the automatic wire arc additive remanufacturing test was performed on the failed crankshaft forging mold to verify the feasibility of the whole scheme.
