Abstract
Coordinate Measuring Machine (CMM) is a vital measuring machine to maintain the quality of the manufactured products. The movement along the three-direction XYZ of the machine during measurement affected by an error that arises from different sources. The measurement uncertainty range of the CMM should maintain through regular calibration. However, the interim calibration is costly and time-consuming as well as there is no specific time schedule for the next interim calibration. In this work, an artefact route for evaluation of CMM is suggested. The artefact is manufactured with certain geometric features and calibrated at NMI (India). The same artefact is again used for calibration the own CMM at shop floor. By this, it is possible to calibrate own CMM any time and as frequently as required. Comparing calibration measurement of the artefact at NMI and shop floor CMM, reliable results are obtained and suggested these routes to industries.
