A free formed curve is applied as a reference model to the edges of the O-ring using the Trend Edge Stain tool. Diameters can vary while the tool continues to stably extract burrs and flaws.
Burrs/flaws were inspected by measuring the diameter of the target. Parts that were not completely round were rejected even though they did not have burrs/flaws. The XG Series Trend Edge Stain tool allows for the stable detection of burrs/flaws.
