Tools for realizing non-stop automatic measurement Fast and accurate vision AF (Auto Focus) The iNEXIV VMA series is equipped with highly repeatable vision AF that offers high-speed, high-precision focusing and height/depth measurement. Non-contact measurement using vision AF does not damage or deform parts, and does not necessitate fixing. Top surface of implant Mid-depth of implant Mid-depth of implant Bottom of implant Even the bottom of a small diameter hole can be brought into correct focus. Laser AF (option) The Laser AF with a long 63 mm working distance is optionally available, enabling height measurement of flat surfaces with high repeatability, in keeping a wide FOV at a low magnification. 63 mm working distance Versatile illuminations The iNEXIV VMA series is equipped with episcopic (top), diascopic (bottom) and 8-segment ring (with 18-degree oblique angle) LED illuminators. Combining these illuminators with superior optics provides accurate detection of low contrast edges. Top light Ring light from rear side Ring light from left side Ring light from right side Any 8-segment light can be selected for effective edge detection. Intelligent search 23 1 Even when a workpiece is misaligned, the system automatically searches the target Recorded location based on the target image recorded in a teaching file, enabling accurate, image automatic measurement by eliminating possible detection errors. 1 Target is detected 2 Searching the misaligned target 3 Target is detected Misaligned target can be automatically detected using intelligent search XY coordinate Digital chart comparator Deviation of contours can be checked by overlaying charts generated digitally from 2D CAD data onto video images. Digital charts always accompany video images. XY coordinate after searching the target 4 Options for expanding measurement possibilities Touch probe for measurement of imperceptible parts from top and bevel angle (option) The VMA-2520/4540/6555 is touch-probe ready and accommodates optional Renishaw® TP20 or TP200 touch probes. Touch probes provide measurements of 3D shapes parts where vision AF cannot be used, such as the inner diameter of an oil seal or the clearance angle of an indexable insert. The touch probe offsets from the optical axis, but works coaxially in the same XYZ coordinate system as the optical axis using iNEXIV VMA TP AutoMeasure software. * The VMA-2520V/4540V/6555V is only for video measuring. Inner diameter of oil seal TP200 Clearance angle of insert Extended 1.5x high-magnification (option) Each model can be modified before shipment to extend magnification to 1.5x, powerful enough for precise measurement of minute electronic parts. * Video measuring images are slightly darker with the 1.5x high-magnification option, even with the same light intensity setting (0 - 100). 0.52x 0.9x 1.5x 2.7x 5.2x Sample: Ø23.5 mm coin 8.9 mm (W) x 6.7 mm (H) 5.2 mm (W) x 3.9 mm (H) 3.1 mm (W) x 2.3 mm (H) 1.9 mm (W) x 1.3 mm (H) 0.89 mm (W) x 0.67 mm (H) Dedicated software to meet measurement requirements User-friendly standard software iNEXIV VMA AutoMeasure The VMA AutoMeasure software provides enhanced ease of use and versatility based on Nikon’s years of extensive experience in developing the NEXIV series. Main program layout Teaching file selection with interactive guides Optional software iNEXIV VMA Profiler/CAD Reader: 2D profile shape analysis program iNEXIV VMA Virtual AutoMeasure: CAD interface off-line teaching support program Gear evaluation software: Analysis of flat gears in terms of pitch deviations, tooth profile errors, tooth space run out, base tangent length, dimension over pin NEXIV EDF/Stitching Express: Image analysis and archiving program for creating an all-in-focus EDF (Extended Depth of Focus) image from multiple images at different Z axis. This also generates a stitched image with super wide FOV from multiple images on the same XY plane. NEXIV EDF/Stitching Express 5
