Evaluation of Uncertainty in Micrometer Indication Error and Application in Measurement of Form and Position Errors
Geometric measurement is widely used in the research and development,production,and manu-facturing of electric motors.Analyzing the quality of measurement results,measurement uncertainty is a measurement.This article first introduced the A-class and B-class evaluation methods and processes for standard uncertainty.Then,through practical examples,the uncertainty of the indication error of the outer diameter micrometer used in daily testing was calculated,and the measurement uncertainty of roundness measurement error using the two-point method of the outer diameter micrometer was explored.
