The Trend Edge Tools can find the best fit circle that correlates with a part and then locate the center position. By detecting the notches in a workpiece at the same time,the XG is able to do high-speed, high-precision rotation angle detection.
Previously, the workpiece was rotated and a fibre sensor was used to detect the notch in order to correct the angle. This method had problems since positioning was time consuming and a drift in the center positions of parts caused detection errors. The XG is able to correct these issues.
