Speedy Comparison: Inspection Efficiency

Automated measurement verification is faster and more reliable than a manual process. However, even a digital optical comparator that works directly with CAD data to compare a part to a CAD file might require an operator to manually align that data to the part. To automate measurement and verification of a part against its CAD data, Methods Machine Tools Inc. has introduced Auto-Align and Auto Pass/Fail software tools for the VisionGauge digital optical comparator from VISIONx Inc., Pointe-Claire, Quebec, which also developed the software.

Auto-Align and Auto Pass/Fail software tools for the VisionGauge digital optical comparator allow end users to automatically compare a part to its CAD data in real time.

The Auto-Align tool automatically aligns the CAD data to the part and supports X-Y and X-Y-rotation alignment of the CAD drawing to the part. The Auto Pass/Fail tool automatically determines, in real time, if a part is within tolerance, supports bidirectional tolerances and does not impose restrictions on the tolerance values. This means tolerances can be standard plus/minus tolerances, as well as minus/minus or plus/plus tolerances.
