| Abstract: | In view of the cosine error in the measurement of the contact type coordinate measuring machine, a method based on the model is proposed. Through the theoretical model extraction measuring curve of 3D vector and calculate the center of the trajectory measurement, the measured center along the model of three dimensional vector compensation, the ifnal determination of the actual contact point of needle and leaf, which can realize 3D measurement and three-dimensional compensation. This method can be used to realize the accurate measurement of the irregular curved surface of the blade, and the advantages of the model based vector measurement method in accuracy and efifciency are veriifed by an example. |
