Abstract
Static stiffness of machine tools is considered as a significant factor as it affects to machine performance and accuracy under load. The main purpose of this paper is to present the uncertainty budgets for static stiffness measurement results. The uncertainty budget has a very important practical aspect. It allows to isolate some components that contribute the most to the combined measurement uncertainty. This paper presents a measurement procedure to measure static stiffness which is in line with ISO 230-1. The conditions that must be met to minimize the considered uncertainty components in the budget of the complex uncertainty are described. The comparison of the results shows that the uncertainty of typical sensors is not the main component in uncertainty budgets. However, conducted analyses indicated some crucial factors that should be taken into account: averaging method, type of signal filtration, influence of environmental conditions or confirmations of the consistency of measuring instruments.
