Utilizing CMM measurements in the evaluation of machine tool accuracy

Author(s): J. Holsa Abstract: This paper presents the theoretical background of a new feature based analysis of co-ordinate measuring machine (CMM) measurements. The same analysis method can be used also to analyse double ball bar (DBB) and cross-grid encoder measurements. In this method test pieces or ordinary workpieces are measured in a CMM and the analysis method is applied to reveal individual deviations in a machine tool. This way it is possible to have a systematic and continuous follow-up of machine tool capability based on deviations. 1 Introduction: The new method for CMM (co-ordinate measuring machine) measurement analysis introduced in this paper endeavours to integrate test piece and direct machine tool measurements. The accuracy of a machine tool can be inspected either by making a direct measure... Pages: 10 Size: 686 kb Paper DOI: 10.2495/LAMDAMAP970441
