Abstract

This paper presents work being performed by NIST to evaluate test methods prescribed by the new draft standard for determination of on-machine measuring performance of numerically controlled machine tools [1]. The measuring performance of a machining center, equipped with a strain gage style touch trigger probing module, is evaluated according to this standard in order to validate the proposed test methods and to generate a baseline set of data to be used in the development of on-machine measurement uncertainty budgets. Probing repeatability, two-dimensional (2D) and three-dimensional (3D) probing errors and errors in identifying the workpiece coordinate system (WCS) in the machine coordinate system (MCS) are evaluated and the results presented.
