VisionGauge® Edge Break Measurement Tool

An edge break consists in smoothing a corner that otherwise would be too sharp, most often using either a chamfer or a radius. The objective is generally to ensure part longevity, safe handling, and proper performance.

There is no GD&T symbol for edge breaks and they are not referenced in the ASME Y14.5 standard. Nevertheless, VisionGauge® systems are perfectly suited for measuring edge breaks, either using overlays or the new VisionGauge® edge break measurement tool.

VisionGauge®'s edge break measurement tool is suited to sharp, rounded, and chamfered edges. The tool automatically locate the edge break's tangent points, to very high accuracy, and there are no limitations as to the angle at which the edges meet.

VisionGauge®'s edge break measurement tool is robust and filters our spurious noise (i.e. disregards point imperfections and defects such as contamination, "mouse-bites", etc...) to obtain the true best-fit line. Measurement results are fast, repeatable, and completely operator-independent.

The VisionGauge® edge break measurement tool also has user-selectable parameters for demanding applications (e.g. the allowed "Delta" variation in distance from the calculated line before locating an edge break, etc...).

This tool is available for both manual and fully-automated measurements (i.e. it can be included in an automated program). The edge break location can be saved as a datum and re-used in later measurements for fast and highly-accurate program results.

VisionGauge®'s edge break measurement tool is fully-integrated into the VisionGauge® Digital Optical Comparator’s software:  This means that VisionGauge’s® multi-level password protection will be available, reports can be produced, all of the data & results can be databased, sent to external applications, etc, etc, etc...
