Abstract:  For turbine disk slots of high-end power equipment such as aero engines and gas turbines, the machining technologies were analyzed from two aspects of mechanical machining (e.g., broaching, milling, grinding) and nontraditional machining (e.g., wire electric discharge machining and wire electrochemical machining), respectively. The development current situations were systematically explained from the viewpoints of design and application of tools, evaluation and control of machining quality. The important achievements of the research work in this field at home and abroad were also introduced. Finally, the development trends were generalized prospectively.

Key words: turbine disc slot, mechanical machining, nontraditional machining, tool technology, machining quality
