Algorithm for remanufacturing of damaged parts with hybrid 3D printing and machining process

In industry, damaged parts are difficult to be replaced. Remanufacturing is a technique that gives a new life to a product. However, remanufacturing of a complex damaged part with various defects is not easy to develop and mostly a single process. In this paper, a hybrid method is proposed which integrates coordinate measuring machine (CMM) data collection, defective model regeneration, and decision making for process selection for the repair, such as materials addition with 3D printing or material removal with machining. The proposed method is demonstrated to repair a turbine blade virtual model to test its efficiency and reliability.
