Method for measuring aero-engine compressor blades based on three-coordinate measuring machine

The invention belongs to the field of measuring techniques, and relates to a method for measuring aero-engine compressor blades based on a three-coordinate measuring machine and applicable to an aero-engine swallow tail-type rabbet blade three-coordinate measurement. According to the invention, when the blades are measured on the three-coordinate measuring machine, a measuring clamp can be shared through double stations and multiple part numbers, different measuring procedures can be formulated, and one measuring clamp can be used for measuring a plurality of various-typed blades, so that the situation that one type of blades uses a set of three coordinate measuring clamp in the prior art is changed, and cost for designing, manufacturing and safeguarding the measuring clamp is saved. When measuring blades in batches, the double-station measuring clamp enables the measuring machine to measure blades on two stations continuously and alternately by formulating circulating measuring procedure, so that the time of
