On determination of sample size in form error evaluation using coordinate metrology
During form error evaluation, as the accuracy requirement increases the measurement sample size should also be increased, thereby increasing the measurement time. In this paper, a new parameter is introduced based on the asymptotic distribution of the range of errors. This new parameter gives the probability that the form error (range of errors) is less than a predicted value based on the current sample size and the corresponding errors. Simulation studies are carried out and the results are presented.
