Originally titled 'Digital Optical Comparator Provides Five-Axis Inspection and Measurement '
Methods Machine Tools Inc.’s VisionGauge digital optical comparator 700 Series developed by VISIONx Inc, features five-axis inspection to efficiently view parts from all sides and angles. The 700 Series is ideal for the automatic inspection of parts with complex geometries found in aerospace and other industries where parts can be challenging to manufacture. The five axes of motion (X,Y, Z, rotary, tilt) enable quick, accurate inspection of all sides and angles on the part, the company says. Powerful "adaptive" software locates features of interest on different surfaces with varying reflectivity and viewing angles. The 700 Series is useful for checking EDM or laser drilled holes, found in aerospace or power-gen turbine components, for example. For both round and shaped holes, the VisionGauge 700 Series automatically verifies hole presence and accurately measures hole location.
The optical comparator is available in a high resolution 20× magnification and features a 38” diagonal image viewing area. Travels of 12” are standard on XYZ axes. An ultra-bright all-LED illumination offers stable, repeatable multi-angle and multi-quadrant illumination conditions via a programmable, computer-controlled system, the company says. The system comes with flexible and general-purpose reflected illumination.
Featuring fully automated operation to remove operator-to-operator variation, VisionGauge digital optical comparators are fast, accurate and easy to use. The systems also feature CAD auto align and CAD auto pass/fail tools. The auto align tool automatically aligns CAD data to the part in less than 2 seconds, producing repeatable and accurate results that are completely operator independent. The comparator's Auto Pass/Fail tool automatically determines, accurately and in real-time, if a part is within tolerance, the company says. The Auto Pass/Fail tool can be point-based or can consider complete geometric entities and can perform both functions simultaneously, on the same part.
