Sažetak
The measurement result if expressed without confidence interval estimate it is not complete. Confidence Interval is characterized as uncertainty and is a quantitative indicator of the measurement result quality. Measurement uncertainty is mainly caused by factors such as measuring instrument, operator, workpiece, applied strategy and/or measurement conditions. GPS, a standard defining geometrical specification and product verification, integrates the entire product geometry description and defines uncertainty at each stage. The result is a total uncertainty which is usually significantly greater than measurement uncertainty (sometimes twice greater). This study provides a method for estimating total measurement uncertainty of determining flatness error using coordinate measuring machines (CMM).
