Paper Abstract

On a commercial roundness measurement instrument METAS has implemented several modifications offering an up-grade of the measurement capabilities and a full understanding of the measurement process. The Talyrond 73 instrument is equipped with a rotating spindle with an oil-hydrostatic bearing. The modifications include an incremental encoder on the spindle, a vibration free DC motor with variable rotation speed for driving the spindle, new amplifier electronics with selectable gain for the LVDT probe, new software for data acquisition and evaluation, and a heat protection shield. The application of error separation techniques, the complete characterization of all relevant parameters and the high level of precision achieved allow the attribute "primary" be given to this roundness measuring machine.
