Description

This Technical Report provides a simplified approach for evaluation of dimensional measurement uncertainty; the method is consistent with “The Guide to Expression of Uncertainty in Measurement(GUM).”
Primary purpose technical report provide introductory guidelines assessing dimensional measurement uncertainty manner less complex presented guide expression (gum).  fully consistent gum methodology philosophy. simplifications include not assigning degrees freedom sources, assuming uncorrelated avoiding partial differentiation always working input quantities units measured.  detailed discussion concepts prove valuable novice experienced metrologist. worked examples emphasis thermal issues, provided. intended design, drafting, mechanical, manufacturing, production, tool/gage, quality, process project engineers, cad/cam/cae specialists, inspectors educators across broad range global manufacturing. special aerospace, automotive, medical device, precision instrumentation related industries. click print-friendly version brochure asme's b89.7 standards guidelines. provides simplified approach evaluation uncertainty; method “the measurement(gum).”
