ADAPTIVE REPAIR APPROACH FOR RECOVERING COMPONENTS FROM DEFECTS

摘要

The geometry of each worn part is unique,so that a repair has to be tailored to each part individually. To ensure that a high quality repair is carried out,tool paths have to be generated adaptively for the unique geometry and pose of the part being repaired. A polygonal modelling approach is introduced to rapidly construct a geometric model of the part to be repaired,together with a defect-free model with identical geometry and poise. The two models are compared so that the defects are identified for direct use by the laser cladding,machining and inspection processes.
