500 Series VisionGauge® Digital Optical Comparator Training Class September 26th & 27th, 2017
(9 am to 4 pm on both days)
A VisionGauge® Digital Optical Comparator 500 Series training class will be held at VISIONx’s facility (Pointe-Claire, Canada) September 26th & 27th, 2017.
The class will start with a short refresher of VisionGauge® Digital Optical Comparator basics and will quickly move on to a review of the latest software enhancements and then onto more advanced topics, including automated programs.
This is a very hands-on class and – as always – we are very happy to look into the specific challenges of your real-world applications with you.
The training will be in English. There is no charge for current VisionGauge® Digital Optical Comparator users and lunch is provided on both days. Participants are responsible for their own travel, lodging and other expenses.
Email firstname.lastname@example.org to sign up, or if you have questions, want for information about nearby hotels, assistance with travel arrangements, etc…
Sign-up closes on September 8th at 5 pm (Eastern Time zone).
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:
400 Series VisionGauge® Digital Optical Comparators are now available in a horizontal configuration. These systems are state-of-the-art inspection and measurement systems in a compact desktop format. The systems feature a large measurement envelope (up to 12″ x 12″), 3 manual stages (X, Y, and Z), high-resolution precision optics, X/Y 0.25 micron resolution encoders, VisionGauge® OnLine software, and much more.
Note that you can obtain an updated product brochure (with specifications, etc) in .pdf format.
To be able to report the absolute location of a feature (such as cooling holes) on a part, a measurement system needs to know the location of the datums relative to which these locations are expressed. Five-axis parts use a six-point datum structure to set the position along the three Cartesian axes as well as the rotation about each of these three axes.
There are two different approaches to establish these datums. The first approach consists in using a fixture that physically comes into contact with the six datum points. And because the fixture is generally designed to easily line up with the un-rotated Cartesian axes (along the fixture’s straight edges, for example or using locator holes, tooling balls or other appropriately-designed simple features), it is quite simple to “zero out” the system’s 5 axes of motion (i.e. X, Y, Z, A and B). So with this first approach, the fixture physically sets the location of the datums in space.
With the second approach, a generally simpler fixture is used to only roughly position the part. So with this approach, features on the fixture are still used to “zero out” the system’s 5 axes of motion, but the resulting coordinate system is only approximate. For every part, the system still needs to accurately locate the datums and mathematically re-orient the part (in a way analogous to how a physical 6-point fixture physically reorients the part in space).
The VisionGauge® Digital Optical Comparator’s “Part Reorientation” tool is a powerful and intuitive tool to carry out 6-point iterative alignment. It uses the 700 Series’ LASER module to accurately locate the part’s surface at the datums, even on parts with complex geometries. The tool converges quickly to a stable and accurate solution. And it is extremely simple to then apply the corrections to part inspection programs. The tool also allows you to set limits on the corrections (to ensure collision-avoidance, for example).

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 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:
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 the CAD Auto-Align™ and CAD Auto Pass/Fail™ tools, the VisionGauge® Digital Optical Comparator is truly revolutioninzing how parts are inspected, quickly and accurately, directly on the shop floor!
