A 2D VIDEO CMM IS TURNING THE
world of standard video measuring upside down. Built along the lines of a photocopying machine, the Flatscope, from Werth America Inc., Orchard Park, N.Y., puts a camera underneath, rather than above, the CMM table. Operators simply place a part in the work area and start the program; the Flatscope automatically scans the part.
The system has a window built into its table. Operators place a part onto this window and close the cover, which provides profile illumination. The CCD camera and optics are below the glass, and a light ring underneath provides surface illumination for the measurement of features where transmitted light is not possible.
Flatscope makes an automatic scan of the full window, and an image of the part is available for measurements in the WinWerth metrology software.
The shop-ready gage measures stampings, gaskets, extruded sections, EDM tools, O-rings, and molded products. Software options provide 2D scanning of free-form contours and CAD-profile comparisons in the Werth Bestfit system. Maximum measuring range is 400 3 200 mm, and parts can reach a 100-mm height. Fixed or zoom lenses deliver overall 2D accuracy down to 0.00035 in.
