| titleOfInvention | Calibration method of large-size articulated arm type coordinate measuring machine |
| abstract | The invention discloses a calibration method of a large-size articulated arm type coordinate measuring machine, and belongs to the field of precision measurement methods. The invention provides a calibration method of a large-size articulated arm type coordinate measuring machine, aiming at the problems that the error parameters of a selected D-H model are not comprehensive and the flexible error is neglected in the existing coordinate measuring machine, so that the operational efficiency is not high and the measuring precision is not accurate; the coordinate value of the measuring head is obtained by each group of data through a mathematical model; constructing an objective function; solving the objective function by using the improved very fast simulated annealing algorithm to obtain an optimal solution; and calibrating the error value of the generalized geometric error parameter in the large-size articulated arm type coordinate measuring machine according to the solved optimal solution. The invention reserves the intermediate optimal solution which can be updated in time during calibration, thereby improving the measurement efficiency and precision. |
