Coordinate measuring machine is a kind of test instrument in high precision. The accuracy is the important performance parameter. A method is proposed to realize the calibration of verticality error for adjacent linear axis about Articulated Coordinate Measuring Machine. The straightness error of two linear axis can be obtained based on Least Squares method through measuring points in their measuring range with a square box in high precision. So the verticality error can be calculated quickly according to mathematical equation. Experiment proves that the calibration method can get the verticality error rightly and effectively. At the same time, a foundation has been done for later error compensation about linear axis. |
