摘　　要：针对航空发动机涡轮级性能试验件快速试制与验证的需求,提出一种采用慢走丝加工航空发动机涡轮盘榫槽的工艺路线。通过工艺试验研究得出了满足涡轮盘榫槽质量要求的重熔层控制工艺方案,并形成了一套适用于航空发动机试验件涡轮盘榫槽慢走丝加工、检测的流程与方法。该慢走丝工艺路线首次应用于航空发动机性能试验件试制,与传统拉削工艺相比,其加工效率提高了约52.5%,加工成本降低了约47.6%。采用慢走丝工艺加工的涡轮盘随涡轮性能试验件完成了多次试验验证,试验后涡轮盘榫槽状态良好,验证了该工艺路线加工涡轮盘榫槽的可靠性,为后续涡轮盘榫槽加工提供了一种思路。In order to meet the requirements of rapid development and verification of turbine stage performance test parts of aero-engine,the WEDM-LS process in the machining of the turbine disk was proposed,and remelting layer control scheme that meets the quality requirements of turbine disk tenon groove was obtained through process test,and a set of process and method for machining and testing of turbine disk tenon groove was formed.On this basis,the tenon processing and detection of turbine disk were completed.Compared with the traditional method,the machining efficiency was increased by 52.5%and the cost was reduced by 47.6%.The turbine disk processed with a turbine performance test piece has been tested for many times,and the turbine disk tenon groove was in good condition after the test,which verified the reliability of turbine disk tenon groove processed by this method,and provided an idea for the subsequent machining of aero-engine turbine disk tenon groove.
