Uncertainty in testing the metrological performances of coordinate measuring machines
No full textPerformance verification of Coordinate Measuring Machines (CMMs) is a key task in quality assurance systems, Test results are influenced by various error sources that affect the test with their uncertainty contribution, therefore the correct identification and quantification of these error sources is a crucial task for a proper estimation of the test uncertainty. The paper discusses the identification of the uncertainty contributions to be taken into account for the estimation of the test uncertainty in connection to three tests for the verification of important CMM subsystems: i) rotary table test; ii) contact scanning probe test; iii) video probe test
