Complete guide to evaluating measurement uncertainty

This book provides a complete guide to calculating the measurement uncertainty associated with tests carried out using the following measuring systems: coordinate measuring machine profile projector and tooling microscope. The aim of this book is to provide all those who take measurements with a simple and quick way of assessing uncertainty contributing to the traceability of the results and demonstrating their reliability. To this end the following steps were carried out: study of measurement systems emphasizing the principle of operation application and construction characteristics; identification of the variables that influence the measurement result of each measurand; mathematical modeling of the measurement process in question as recommended by GUM (2003); implementation of uncertainty calculation scripts using the Excel program; carrying out tests to obtain the data needed for simulation uncertainty evaluation with the respective discussions and finally validation of the spreadsheets. Excel proved to be a powerful tool for implementing the calculation scripts for obtaining measurement uncertainty.
