The VisionGauge® Digital Optical Comparator's patented CAD Auto Pass/Fail™ tool allows you to automatically determine, very accurately and in real-time, if a part is within tolerance.

 

The VisionGauge® Digital Optical Comparator’s patented CAD Auto Pass/Fail™ tool accurately computes and displays, in real time, a part’s deviation from nominal, to automatically determine with a Pass/Fail result if a part is within tolerance.

Bone screw teeth verification with the VisionGauge® “Tooth Checker™” tool

 

VisionGauge®’s powerful and innovative new Patent Pending “Tooth Checker™” tool automatically locates, to very high accuracy, the crests and / or roots of  a part’s teeth or threads and determines if they are within their tolerance band.

True Position measurement of a cylindrical feature inspected using Cartesian basic dimensions

 

Easily define features with datums, then automatically determine if the Actual occurrence of a feature falls within the Nominal’s allowable tolerance zone with VisionGauge® OnLine’s True Position measurement tool (Position Tolerance).

True Position Measurements (Position Tolerance)

VisionGauge® OnLine programs can take advantage of our new True Position measurement tool. True Position (sometimes referred to as “Position Tolerance”) is the total permissible variation that a feature can have from its “true” position. VisionGauge® OnLine’s approach to True Position allows a user to define a Nominal feature whose position is compared to the Actual occurrence of that feature. Features are defined using datums that have been set in previous program steps, using VisionGauge® OnLine’s rich measurement toolset to specify points. Nominal features can be defined using either Cartesian or Polar coordinates, which makes this software tool versatile in solving different types of applications. Nominal features can also be offset from a position using Basic Dimensions in the current measurement units.

VisionGauge® Online presently supports Cylindrical (point location) and Non-Circular (line) features of size. The Nominal tolerance zone is displayed along with the Actual feature location. As with all VisionGauge® Online measurements, results – including a Pass/Fail result – can be automatically output to Data Groups and other reporting options.

True Position – Cylindrical (Cartesian)

In the above example, the hole’s nominal center point is defined precisely 1.250 inches vertically and horizontally from the corner of the part. The actual center of the hole is located, and the software automatically computes the True Position of the feature and reports a Pass/Fail result based on the diametric tolerance zone defined.

True Position – Cylindrical (Polar)

In this example, the hole’s nominal center point is defined precisely at 60 degrees clockwise on a radius of .750 inches centered about the part’s center hole. The actual center of the hole is located, and the software automatically computes the True Position of the feature and reports a Pass/Fail result based on the diametric tolerance zone defined.

True Position – Non-Circular (Polar)

In this example, the nominal centerline is defined precisely at 45 degrees clockwise and centered about the part’s center hole. The actual centerline of both teeth on the spline is located, and the software automatically computes the True Position of the feature and reports a Pass/Fail result based on the tolerance zone defined (equidistant and parallel to the nominal centerline).

CAD Auto-Align™ – Automatic CAD Overlay Alignment

Automatic CAD Overlay Alignment with CAD Auto-Align™

 

The VisionGauge® Digital Optical Comparator’s ground-breaking CAD Auto-Align™ tool automatically aligns the CAD data to the part.

The VisionGauge® Digital Optical Comparator's CAD Auto-Align™ tool automatically aligns the CAD data to the part.

The CAD Auto-Align™ tool is very fast (it typically takes a second or two at most) and it produces repeatable and accurate results that are completely operator-independent!

The operation of the CAD Auto-Align™ tool is extremely straightforward. To run it, simply press the “Auto-Align” button:

VisionGauge® Digital Optical Comparator's CAD Auto-Align tool makes aligning a CAD file as simple as clicking a button.

Checking the “XY” checkbox next to the Auto-Align button tells the Auto-Align tool to only carry out X,Y alignment, and to leave the CAD overlay’s orientation unchanged. This is especially useful when adapted fixturing already ensures that the part is properly oriented relative to the CAD overlay.

Checking the “R” checkbox indicates that a rotation-only alignment should be carried out. This is especially useful in the case of parts that are much larger than the system’s optical field-of-view. In this case, the following procedure is a common practice:

    • go to one extremity of the part and carry out a full X,Y,Rotation alignment,
    • set the CAD’s center of rotation at that position (with the “User” button),
    • and then to go to the other extremity of the part and carry out a rotation-only alignment (and thus not translating anything in the previous field-of-view).

 

This is a very efficient and accurate way to align a CAD file to a very large part.

When the “XY” and “R” checkboxes are both unchecked then the Auto-Align tool carries out full X, Y and rotation alignment of the CAD overlay to the part.

The VisionGauge® Digital Optical Comparator’s powerful Auto-Align tool allows you to drastically reduce inspection times and obtain increased accuracy. It can line the CAD drawing up to the part along one or multiple datums, or it can do a “best fit” alignment. You can easily apply it to meet the requirements of your specific application!

Many VisionGauge® Digital Optical Comparator users combine the Auto-Align and Auto Pass/Fail tools to fully automate their inspections:

  • The operator loads the part in the fixture and scans the barcode on the traveller.
  • This causes the VisionGauge® Digital Optical Comparator to load and run a part-specific program that automatically:
    • Reads-in the correct CAD file
    • Auto-Aligns the CAD file to the part
    • Produces an Auto Pass/Fail result that is collected in a Data Group and sent to Excel or an other external application…
    • In the case of parts that are larger than the system’s optical field-of-view, the stage moves the part and carries out the Auto Pass/Fail inspection at however many different locations are required. This way, the whole part gets inspected without having to “shift the overlay”. The CAD data tracks the part’s movement!

 

With our patented CAD Auto-Align™, CAD Auto Pass/Fail™, and patent-pending Tooth Checker™ tools, the VisionGauge® Digital Optical Comparator is truly revolutionizing how parts are inspected, quickly and accurately, directly on the shop floor!

CAD Auto Pass/Fail™ – Automatic Pass/Fail Results

Automatic Pass/Fail Results with CAD Auto Pass/Fail™

 

The VisionGauge® Digital Optical Comparator’s patented CAD Auto Pass/Fail™ tool allows you to automatically determine, very accurately and in real-time, if a part is within tolerance.

The VisionGauge® Digital Optical Comparator's patented CAD Auto Pass/Fail™ tool allows you to automatically determine, very accurately and in real-time, if a part is within tolerance.

The CAD Auto Pass/Fail™ tool can be either point-based or it can consider complete geometric entities. In point-based mode, the part’s deviation from nominal is evaluated at precise user-specified cross-sections to verify that the part is within tolerance at all of these locations. And the geometry-based CAD Auto Pass/Fail™ tool verifies that the part is within tolerance over complete geometric entities. Note that the control-section-based and geometry-based CAD Auto Pass/Fail™ tools can be used simultaneously on the same part!

The CAD Auto Pass/Fail™ tool can be either point-based or it can consider complete geometric entities on VisionGauge® Digital Optical Comparator
With the VisionGauge® Digital Optical Comparator you can specify bi-directional tolerances at various control sections. The system then automatically computes and displays, in real time, the part's deviation from nominal at every control section and automatically displays a pass / fail result at every control section as well as for the overall part.

Also, note that there are no restrictions on the tolerance values. So tolerances can be either the standard “plus/minus” tolerances, as well as “minus/minus” or “plus/plus” tolerances.
