Abrasive cutting wheels spin at extremely high velocities such that anomalies in the density of the wheel (that is, uneven or low-density regions within it) can pose danger to users. Cheyney has integrated x-ray measurement of a wheel’s mass with laser measurement of its thickness in order to precisely map the density across the entire thing. In essence, the process determines the spot density of each point all over a 0.5-mm matrix across the entire surface of the wheel. The system ends up with more than half a million points scanned on each wheel, as part on an in-line inspection and quality control process.
