Inspection Manager Now Supporting Automated Drawing Revision Control
HIGH QA, a leading developer of 2D automated ballooning and GD&T solutions, announces the release of version 3.8 of its revolutionary Inspection Manager software featuring an automated Revision Control module.
The Revision Control module helps users avoid hours of redundant work when the quality control department receives a new revision of a drawing.
The software facilitates a smooth transition from the current drawing revision while keeping intact all balloons, dimensions, and data that have not changed from the previous version. Revision Control Wizard guides users though the drawing update process, clearly marks the differences between the old and new drawings, and helps make new revision balloon adjustments. Newly added dimensions can be automatically ballooned in just one click.
Adding the Revision Control to Inspection Manager's powerful automation capabilities, supplements a set of modules that include: automated ballooning and GD&T extraction, generation of an inspection plan, and creation of inspection reports, such as FAI, PPAP, and more.
"Our main objective is to streamline the inspection process, eliminate bottlenecks, and automate processes that traditionally have been done manually," said Sam Golan High QA Founder and Chairman. "We keep an open line of communication with our clients to receive their feedback on our products, listen to their needs and challenges, and develop solutions that target their goals. Revision Control was 'born' to help our clients keep track of changes and revisions to the original blueprint with a few clicks of a button."
As part of High QA's commitment to a high level of customer service, its loyal customers will receive the Revision Control module at no additional charge.
Adopted by clients in the aerospace, automotive, medical, and manufacturing industries, Inspection Manager has already been proven to improve efficiency, productivity, and profitability.

Next Generation Laser Trackers Increase Portability and Ease of Use
Hexagon Metrology launches a new range of all-in-one high-speed laser trackers
Leading metrology solutions developer Hexagon Metrology today unveiled the Leica Absolute Tracker AT960, a walk-around coordinate measuring machine that fits in a single flight case. The latest model in the Leica Absolute Tracker range, the AT960 answers customer demand for a genuinely portable laser tracker with high-speed dynamics and six degrees of freedom (6DoF) capabilities.

With a complete range of Leica laser tracker accessories built into the device, the AT960 measures to a Leica T-Probe, Leica T-Scan or reflector straight out of the box. Hot-swap battery function and IP54 certification for use in even the toughest workshop conditions mean the AT960 really can be taken anywhere.
Also launched today is the Leica Absolute Tracker AT930 system. With all the features and functionality of the AT960 without the 6DoF compatibility, the AT930 offers a totally transportable 3D solution with unprecedented dynamic capabilities and real-time operation.
“The new AT960 and AT930 laser trackers feature the latest electronics and optical technologies. Leveraging the recent developments of PowerLock, absolute interferometry and optical miniaturization we are able to release next generation portable products based on proven features,” explains Duncan Redgewell, General Manager, Leica metrology products. “The AT960 and AT930 replace the hugely-successful AT901 and T-Cam products and complement the basic Leica Absolute Tracker AT402. We now offer the most complete and modern range of laser trackers available on the market, giving our customers the opportunity to choose the right equipment for their specific needs.”
The Leica Absolute Tracker AT960 and the Leica Absolute Tracker AT930 are available to order immediately through your local Hexagon Metrology commercial center or distribution partner. The Leica Absolute Tracker AT960 will be shown at HxGN LIVE Local at Hexagon Metrology’s Lake Forest Solution Center (Lake Forest, CA) Wednesday, November 12, from 9:00 a.m. to 4:00 p.m.

The CMM Handbook Version 6
CMM Quarterly Publications announces the newest version of The CMM Handbook. This version, version 6, has added an expanded GD&T section, a complete section on Profile, and more in-depth articles on CMM methodology.
Now take your CMM knowledge to a higher level with The CMM Handbook and accompanying videos. With expanded explanations and examples, this book will add to your knowledge of how the CMM is calculating your measured results.
This book is not a training manual on a specific software but an educational resource.
Calypso - Form Datum
What the Form Datum does is establish a FUNCTIONAL Datum Reference Frame coordinate system, similar to if you were setting up the primary, secondary, and tertiary datums on a functional checking gage. This is ONLY for a datum reference frame and does not modify how the base and secondary alignments evaluate their respective coordinate system. In the screen shot below, you can notice the different origin points are for a base alignment and datum reference frame.
To set the Form Datum correctly click on Extras/ Settings/ Measurement/ Form Datum, check both the Outer Tangential Element and the Re. Calculation as per ISO 5459 boxes.
What is happening?
When we create our base alignment the alignment uses the intersection point of your features as below.
This is based on the measurement of the actual features of the part.
Form Datum uses the highest contact points that would touch a Datum Feature Simulator, in order of primary, secondary, and tertiary features, establish a real coordinate system. Calypso will establish the proper location through the form datum reference calculation per ISO 5459. Again this is ONLY used for a Datum Reference Frame and does not affect the Base Alignment.
Form Datum Applied.
As you can imagine this will affect your location and true position results.
Bilateral Equal Tolerance - Calypso
A common question about profile is, if I take the minimum and the maximum values of my profile output they don’t add up to the profile results value. What is happening with the profile calculation?
Let’s look at one of the profile tolerance zone shapes.
Bilateral (Equal Distribution)
Let’s break down this picture above:
The black line is the Nominal Geometry.
The green line is the actual profile.
The blue lines are as designated, the upper and lower tolerance lines. Taking the blueprint tolerance and dividing that number by two, i.e. 0.10 is +/- 0.05 will assign the position of these lines.
The red lines are the actual reported profile deviation. This is where things won’t seem to add up. If my min is -0.0006 and my max is 0.0009 why is it not reported as 0.0015? Instead Calypso reports the profile as 0.0018. Calypso takes the point with the greatest deviation from the nominal geometry and doubles that result for the actual profile result.
Where A is the absolute value of either the min or the max the actual profile deviation = 2xA.
1. Find the maximum value, or the largest deviation toward the outside of the part
2. Find the minimum value, or the largest deviation toward the inside of the part
3. A = The largest absolute vale of either the min, or max
4. Reported Actual profile deviation = 2xA
Max: .0009
Min: -.0006
A = 0.0009
Profile Actual = 2xA = 0.0018
NOTE FROM EDITOR: Although this article is focused on Calypso this formula is used in all softwares to calculate Bilateral Equal Distribution.
