Test Specific Uncertainty Analysis of Zirconia-Dolerite Ball Plate by Monte Carlo Simulation

Surface Plate Based Method for Quick Check CMM Accuracy Measurement

“…Also the precise definitions of uncertainty points reflects the total accuracy of CMM [2]. The Type B GUM method is not a practical solution for CMM, as material properties continuously varies and cost of repetitive measurements are very high [3]. On the contrast Type A GUM method recommends evaluation of condition under the same repeated measurements with Standard Deviation as the indictor of uncertainty measurement.…”

“…On the contrast Type A GUM method recommends evaluation of condition under the same repeated measurements with Standard Deviation as the indictor of uncertainty measurement. Simulation measurement presented in [3] is a time consuming process. 2D dimensional standards like hole plate artefact, ball plate artefact, ball bars effectively measures the performance of CMM, as they can be oriented in 3D space effectively, provided that no external support is given to them.…”

“…2D dimensional standards like hole plate artefact, ball plate artefact, ball bars effectively measures the performance of CMM, as they can be oriented in 3D space effectively, provided that no external support is given to them. External support increases the complexity of thermal interactions and in turn affects uncertainty in measurement [3,4]. The calibration comparison of 2D dimensional standard is taken into consideration for error computation [4].…”
