Optical Analysis of Shape and Roughness of a Gear Wheel

Quality control in industrial production of gear wheels requires quick measurements of shape and roughness, and wear volume. The optical inspection of the gear wheel is difficult, because of the steep walls and because of the absolute height of the wheel. This application note demonstrates that the Axio Zoom.V16 is excellent to observe and measure features in the vertical and horizontal contour easily. The confocal laser scanning microscope LSM 700 extends the optical metrology onto measurements of wear volume and roughness.
