Evaluation of coordinate measurement uncertainty of parallelism of axes by means of sensitivity analysis method
Keyword(s):
The examples of measurement of three variants of the parallelism of the connecting-rod center axes the theoretical basis of a new method for estimating the uncertainty of coordinate measurements. This is a continuation of the article “Estimation of coordinate measurement uncertainty – theoretical fundamentals” (Mechanik 11, 2018). In the first variant, this tolerance field is in the form of a cylinder, in the other two it has the form of a pair of planes. In the examples presented, uncertainty budgets contain six or nine input factors. In all cases, when the axes of the measured holes are parallel to one of the machine axes, only two input factors affect the uncertainty of the measurement of parallelism deviation.
