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).

We’re happy to introduce VisionGauge®’s Patent Pending “Tooth Checker™” tool, specially adapted to check parts with teeth. This innovative new tool automatically locates, to very high accuracy, the crests and / or roots of the teeth and determines if they are within their tolerance band. It can also determine all other part characteristics, such as tooth pitch, thread depth, major & minor diameters, etc…
The Tooth Checker tool can verify that either crests, roots, or both, are in tolerance, using these crest & root points that the Tooth Checker tool has found, it can then automatically determine all other part characteristics:
This powerful new tool is perfect for quickly and accurately checking:
The VisionGauge® Digital Optical Comparator’s new “Min/Max” software tool is the perfect solution for automatically aligning a part using a rotary stage. The tool can be setup to rotate the part and find the position that either minimizes or maximizes a dimension.
Common examples include the following:
With this new Min/Max tool, it’s extremely easy to setup an automated routine for the alignment of any kind of part. Also, results are extremely repeatable. This advanced tool uses high-order interpolation for very accurate subsampling. This means that the position of best alignment can be found very accurately, at any orientation (not just at the sampled orientations).
This new tool is completely integrated with all of the VisionGauge® Digital Optical Comparator’s other tools so that all of its results can easily be recoded, transmitted, databased, sent to Excel™ or any other data capture application, put in a report, etc…
This new Min/Max tool further increases the wide range of applications that can easily and reliably be solved using the VisionGauge® Digital Optical Comparator.
VisionGauge® Digital Optical Comparators are being used by many different companies across a very wide range of industries. Here are some examples of applications we have solved within various industries:
In this case study, Paradigm Precision (a large aerospace sub-contractor to GE, UT, Rolls Royce and many others) explains how they are using the VisionGauge® system to carry out 100% inspection of cooling holes on a wide range of complex 5-axis parts, including blades, vanes and heat shields.
They mention that they are achieving a repeatability of +/-0.0001″.
This new higher-magnification configuration was developed to meet the requirements of various higher-magnification applications, such as the fast and accurate inspection and measurement of diamond Electrical Discharge Machined Polycrystalline Diamond (PCD) and Cubic Boron Nitride (CBN) cutting tool inserts.
