Abstract: A special checking device is chosen as an example to show a method for position error based on CMM using datum bridging principle. Mathematical model for parallelism and perpendicularity is calculated and deduced, and the measurement procedure is introduced. The measurement range and ability are improved. Meanwhile, the uncertainty of measurement results is evaluated, and the bridging method is proved feasible.
