The geometry shape and parameters of highefficiency cutting tool directly affects the tool’s service life and product’s quality in advanced manufacturing technology. Thus, a noncontact measurement method based on surface structured light projection is adopted for geometry parameters of highefficiency cutting tool. This method can not only reconstruct the 3D model of the tool used for measure its geometry parameters, but also can directly detect the defects of the tool surface. This work mainly focuses on the basic ideal of surface structured light projection, mathematical model of measurement system and point cloud rotation registration. The transformation relation between tool turntable coordinate system and CCD camera imaging coordinate system is built. Meanwhile, the measure experiments on was carried out, the experimental results on straight shank twist drill show that the surface structured light projection is effective and precise in the tool measurement.
