The article discusses the influencing factors and optimization of coordinate measuring machines (CMMs). It provides an overview of the resolution, specification, and process capability of CMMs which are often used to measure workpieces that have tight manufacturing tolerances. It explains the factors that influence measurement uncertainty including properties of the feature to be measured, effects of the operator, and environmental condition and the different methods to determine uncertainty.
