In this paper, the current manufacturing status of aero-engine blades is taken as the research object. We made a brief overview of ECM, CNC machining, precision forging, the key technologies and measurement methods used in manufacturing of aero-engine blades. The implementation of coordinate positioning, measurement trajectory planning and noise reduction of coordinate measurement is also considered. And then we analyze the influence of laser probe installation accuracy,laser projection angle, depth of field on laser scanning measurement, which has certain guiding significance to the development of precision manufacturing and efficient testing technology of aero-engine blades.
