AACMM evaluation test From the above data sets mean error and standard deviation for diameter are obtained and represented for each position. Total standard deviations of 0.0136 and 0.0181 mm and ranges of 0.0709 and 0.0828 mm (laboratory 1, circle 1 and 2 respectively) have been found. In laboratory 2, test measurements results on standard deviations of 0.0107 and 0.0116 mm and ranges of 0.05601 and 0.0610 mm. Fig. 2 shows the variation of the center error and its standard deviation per gauge position. 

According to AACMM evaluation test results, it has been noted that positions 1,2,3 and 4 gives the best results in terms of errors and standard deviation although most of the results are in agreement with the technical specification, as well. The worst behaviour for the rest of the positions could be explained by the gauge positions that force to measure in an uncomfortable and unstable operator pose. It also can be because of extreme positions, near to the AACMM limits.
