Abstract: Laser metal deposition with powder additive/subtractive hybrid manufacturing technology is an ideal candidate processing for repairing and remanufacturing of high value tools and dies. In order to improve the efficiency and accuracy of die repairing, the process of die repairing by using the additive/subtractive hybrid manufacturing technology is studied. In the first, the optimal repairing parameters are determined according to the specific operating conditions and material performance requirements. In addition, the application conditions and scope of the repairing process are also discussed. It is demonstrated through the experimental results that when the present technological plan is applied, the die can be repaired without stitching traces, and the hardness increased by 7.4 HRC, the performance of the die is improved.
