Abstract
An important step in turbine repair is the re-contouring process as it determines part and surface properties. Re-contouring is performed subsequently to the material deposit and has to be adapted to each repair case individually. Especially, part distortion is a crucial aspect in terms of quality and has to be considered in process design. This paper introduces a novel method for evaluation of re-contouring processes regarding part quality and, especially, part distortion. For this purpose, a simulation model for calculating local cutting conditions is introduced and validated experimentally. The validation is carried out for a thin-walled analogue part. The results reveal a clear dependency between the absolute part distortion and the surface generating cut volume (SGCV).
