Calculating uncertainty of 1-D measurements on a coordinate measuring machine
This presentation is a quick review of the actions taken to calculate the uncertainty of measurements made along one axis of the M-60 Coordinate Measuring Machine (CMM). National Institute of Standards and Technology (NIST) Technical Note 1297 `Guidelines for Evaluating the Uncertainty of NIST Measurement Results`, was used as a guide to define what actions would be taken. Very simply stated, TN 1297 says that the uncertainty of a measurement result consists of a combination of several components (sources of variation) in the measuring process. The basic approach is to represent each component of uncertainty by an estimated standard deviation. These standard deviations are then combined by the `root-sum-of-squares` technique to arrive at the estimated standard deviation of the measurement result.
