【Abstract】 This paper concerns with the error correction for the CMMs by a compute- r. The lattice computation is proposed and the mathematical model of error correction formulated and programmed. As an example the model of error corr- ection for A221 CMMs is used. The coordinate error of measuring point can be controlled within two microns. It has been found that the new method is very useful. In order to improve the accuracy and the rate of detection, a new dete- cting device-translational ball detector-is being designed.更多还原
