Abstract The coordinate measuring machine (CMM) uncertainty for evaluating the form errors-oriented measurement tasks has been systematically studied, thus the rapid and reliable evaluation of the CMM measurement uncertainty can be realized.Two uncertainty combined methods based on Guide to the Expression of Uncertainty in Measurement (GUM) and Monte Carlo method are provided.The feasibility of the evaluation method has been verified by measurement example of flatness.The experimental result shows that precision significance of uncertainty determined by GUM is unreliable, the expanded uncertainty increased by 11.1% compared with actual situation.To systematically solve the problem of the CMM uncertainty for evaluating the measurement tasks targeting form errors is typical and representative, which can be effectively applied to solve the uncertainty evaluation problems of other precision instruments.
