EXPERIMENTAL ANALYSIS OF INDUSTRIAL COORDINATE MEASURING SYSTEMS USING A CALIBRATED PRODUCTION WORKPIECE

摘要

The measurement of a part on a coordinate measuring machine may be affected by many factors such as the machine accuracy itself, the measuring environment, the probe configuration, and the measuring strategy. In order to understand the effect of some of those factors on industrial-grade machines, a master production workpiece has been circulated in Brazilian industries for measuring particular GPS features according to a predefined master measuring protocol. Conclusions could be drawn about the behaviour of each machine under varying conditions, the measurement divergences from one similar machine to another operating under distinct conditions, the complexity of measurements with CMMs, and the need for good measurement practices in the productive sector.
