Turbine film cooling technology is widely used in high thrust-weight ratio aero engine nowadays, so the accuracy in manufacturing of turbine film cooling holes will directly affect the performance of the engine. The film cooling micro-hole has the characteristics of small diameter, high quantity, high depth-diameter ratio, and complex spatial angle, which has a complicated fabrication processes and high precision requirements. The drilling technology and equipment for film cooling holes abroad are strictly kept secret, while, there is still a fact that the low forming and unsteady quality of film cooling holes produced domestically. Therefore, it is of necessity to make a summary of the current situation and development trend of producing film cooling holes for turbine blade to provide a reference for the development of film cooling hole manufacturing technology and its equipment. In this paper, the necessity and importance of the film cooling hole accuracy are summarized and the state-of-the-art manufacturing technologies for producing drilled cooling holes are analyzed, and then, the research content and the solution to the key problems for the film cooling hole drilling technology are proposed based on the analysis. Moreover, in view of the need for precise measurement of the film cooling holes, the existing film cooling hole measurement technol  y is introduced. Finally, the development trend of drilling and measuring film cooling hole of the hollow turbine blade is generalized according to their technical status and key problems.
