Method of determining the measuring uncertainty of a coordinate measuring device |
摘要 |
To determine the measuring uncertainty of a coordinate measuring machine, a real measurement is first made of a workpiece, with any compensation provided for on the machine disabled, to obtain a measured value of one or more required quantities; a predetermined number of simulation cycles are then performed according to the Monte Carlo method to statistically vary a given number of influence parameters affecting the measurement and generate simulated values of the required quantity; and the measuring uncertainty value is determined by statistically analyzing the deviations between the simulated values and the measured value.
