| Abstract Scope |
Manufacturing single crystal aero-engine blades is one of the key technologies to improve the reliability, durability and performance of aero engines. Usually a precision machining process is needed for the cast surface to reach the desired dimensional precision and surface quality. During machining processes, however, plastic deformation induced recrystallization leads to crack initiation and propagation along the grain boundary. In this study, the cast blades were ground and polished by an adaptively-controlled abrasive belt grinding process. Finite element analysis of abrasive belt grinding for single crystal aero-engine blades was performed. In addition, a metamodel was constructed to couple the FE simulation with an optimization procedure whose objective is to minimize recrystallization. Ultimately, abrasive belt grinding experiments were conducted to validate the numerical study. The results of simulation and experiment show good agreement and proper process settings were found from the optimization study. |
