Digital optical comparatorsMarch, 01 2011
Methods Machine Tools, Inc. has announced that they are the distributor of VisionGauge Digital Optical Comparators throughout North America. The comparators, developed by VISIONx Inc. of Pointe-Claire, Quebec, claim to offer many advantages over conventional comparators, including the ability to digitally compare a part to its CAD data.
This data can be archived electronically. The system automatically produces an operator-independent “pass/fail” result, and displays any deviation from specification by comparing a part against bi-directional tolerances at user-specified control points. Similar to a CMM, the comparators produce accurate measurements in both manual and fully automated modes. The comparators feature a set of machine vision tools to carry out pattern matching, color verification, defect detection and more. A very high resolution imaging system features detailed inspection of subjective properties, such as surface finish verification, digital image collection, annotation and electronic distribution.
