Can somebody help me on this please? I am doing Proficiency Testing for 3D on CMM. I got everything measured what was required, but I am not sure how to calculate uncertainties. I have never done uncertainty before.
In the scope shows (43+0.001L) microns and the Uncertainty Budget show slightly different 44 microns +0.0001531microns/mm for the same CMM. Budgets were done but person who worked here before.Now I have to report Diameter 85.003mm and Angle 89.383 degree. and uncertainties for those. Can somebody show me how to do it correctly so I can calculate the rest of the uncertainties for all of the measurements that I need to report please? Thanks!!!!!
