Within the scope of the transfer project, the findings from CRC with regard to the automated planning of the re-contouring of compressor blades are transferred to the re-contouring of fan blades, taking into account an individual target shape. For this purpose, the automated planning algorithm from subproject C1 is generalized, focusing on the determination of an individual target shape, the automated adaptation of the tool path taking into account the local allowances and the transfer of the geometric simulation model. This tool is used to determine the influence of process control variables on dimensional accuracy. For this purpose, the simulated process parameters within a test series are compared with the with the actual shape. This results in a set of rules for re-conturing which is integrated into the current repair process in conjunction with the automated planning algorithm.
