Digital Optical Comparator with Extended Travel

Methods Machine Tools, Inc. has introduced the extended-travel 700 Series VisionGauge Digital Comparator manufactured by VISIONx INC.

The extended travel machine features a 24" x 24" x 24" envelope and tilt and rotary axes based in a trunnion configuration, which can accommodate parts weighing up to 100 lbs. The system configuration is suited for larger and heavier parts such as those found in the industrial gas turbine industry.

The 700 Series VisionGauge has 5 axes of motion (X, Y, Z rotary and tilt) to enable a user to accurately view parts from all sides and is fully automated, eliminating operator-to-operator variation and potential error. The 700 series is particularly suited for the inspection of EDM and laser-drilled cooling holes, can automatically verify hole presence as well as accurately measure hole location and geometry, and has the ability to measure complex parts made via additive manufacturing. It supports both round and shaped holes and works equally well on both coated and uncoated parts. An ultra-bright, computer-controlled multi-angle, multi-quadrant and all-LED illumination via a programmable, computer-controlled system is standard on all machines. The system has complete integrated 5-axis correction and dynamic fixture correction, as well as full 3-D mapping for maximum accuracy.

Introduced in 2014, the original 700 Series VisionGauge has a 12" x 12" x 12" envelope and a tilt and rotary stage assembly that is mounted in a cantilever configuration. This is designed for inspecting smaller, lightweight parts such as blades, vanes and heat shields in the aerospace industry.

"The 700 Series VisionGauge now offers an extended-travel version that can inspect large, heavy parts. This fills a definite need in the inspection and measurement world," said Steve Bond, National Sales Manager, Methods Machine Tools, Inc.

The VisionGauge has an optical system designed for an extended depth of field, providing complete clarity and focus, regardless of a part's geometry, in addition to a very long working distance that provides enormous flexibility. The system has innovative and adaptive feature-detection software tools that accurately locate holes and slots on different surfaces, with diverse reflectivity and at various viewing angles. This is especially helpful when dealing with burrs and splatter.

VisionGauge Digital Optical Comparators are a fully-digital drop-in replacement for traditional optical comparators. The comparators work directly with the part's CAD data and do not require any overlays, Mylars or templates. Systems are Windows-based and delivered network-ready in a shop-floor, convenient "rolling cart" configuration. "VisionGauge Digital Optical Comparators are more accurate than traditional optical comparators and allow users to achieve a much higher throughput," said a Methods spokesperson. The comparators can be set up to automatically collect complete electronic documentation and device history for SPC and quality compliance purposes. VisionGauge Digital Optical Comparators allow users to compare a part to its CAD data in real-time, fully automatically. VisionGauge Digital Optical Comparators are available in vertical and horizontal configurations and are exclusively distributed throughout North America by Methods Machine Tools, Inc.
