One gear to rule them all

Good news, everyone: gear inspection just got easier! This has to do with the implementation of the Gear Data Exchange format, and you don’t need your GED to use GDE. The GDE format has been developed since 2003 and is described most recently in the relatively short VDI/VDE 2610 standard.

The purpose of GDE is to have a universal format that describes all geometric parameters for cylindrical gears which can then be easily transferred between design, manufacturing, and quality departments. The format is based on Extensible Markup Language (XML) Version 1.0 which is easily able to be implemented to already existing database applications. In a sense, it can be thought of being the DMIS for gears.

Imagine a recipe where, across the world, anyone can decipher what the meal is supposed to look like at the end no matter if you grow the food, package the food, or cook the food. This same advantage will make it possible for gear data to be easily transferred and interpreted faster and with less mistakes no matter what software, machine, or controller you’re using. This is because GDE eliminates errors and unnecessary delays such as entering data manually incorrectly from a part print whose resolution is low from the way it was sent electronically.

Now, GDE has come to your favorite software: TGear! TGear is not only able to read in .xml files but it can also output your programs into .xml files as well. The .xml files themselves are so well structured and organized with ASCII text that even novice users can identify mistakes easily.

To give you an idea of the simplicity of a GDE file, the main sections are “Identification”, “Geometry”, and “Inspection”. These sections are, of course, broken down into further subsections as needed in order to completely describe all pertinent gear parameters. Further information can be input in a “User” section as well if necessary. VDI regularly updates “complete” structure files (.dtd) files which you can think of as empty GDE files that can be used as the basis to create your own GDE files as you see fit to describe your gear. You can download the latest files here and you can open  them in the simplest of text editors like ‘Notepad’.

If you would like more information about GDE, a sample file, and to see how it is implemented in our gear software, please don’t hesitate to contact me at or check out our website here. Happy measuring!

What’s New Pussycat? Whoa, Whoa Whoa!

Every year the Wenzel sales staff from around the world descend on Wiesthal, Germany for a week of training and product introductions. With 2016 being my first time to the sale conference and I was floored by the new technologies I was introduced too. 

What technologies you may ask? Well, it’s top secret, but it will be released at the 31st annual Control Show this May 9-12 in Stuttgart. Wenzel will be in hall 5 at booth 5102 and we hope to see you there!  What I can give you now is a review of our current offerings and what they are best used for so you can appreciate the changes when they come. 

LH Generation CMM

The LH CMM is Wenzel’s flagship CMM hand builtd in Germany. It has high accuracy, smooth drives and thick granite. This system is perfect for scanning or measuring precision parts large or small. The LH has the widest range of sizes from a shop floor 5.6.4 to a very large 15.60.12. It also has the most options when it comes to probing. An SP80 or PH10M with an SP25 are great options although but the REVO is its specialty. 


CORE is an optical CMM system with 5 or 6 axes that is typically 5 times faster than a tactile measuring machine. The CORE is ideal for turbine blade inspection, medical implant measurement, or any other parts with polished surfaces and sharp edges. This machine is shop-hardened and has a small footprint. 

The CORE machine can measure blades and other parts from 1” to 80” tall and, unlike other non-contact systems, it can be calibrated to ISO 10360 just like a CMM. The CORE uses a high intensity spot of light to measure parts instead of a traditional tactile probe.  It is very fast, accurate, repeatable, and reliable.


The XO CMM gives customers a lower cost option to the LH CMM that features the accuracy and quality that customers have come to expect from Wenzel. These CMM’s have granite bearing ways and work best with a PH20 or PH10. Choose an XO to measure machined components, stampings or tooling with the precision of a 2.5micron system. 

exaCT Computed Tomography System

The exaCT Computed Tomography machine uses x-rays to produce three-dimensional representations of the scanned object both externally and internally. This opens a whole new world of metrology including assemblies, porosity, internal dimensions, and non-destructive testing. 

It is important to note that the exaCT is more than a lab device. It is a metrology grade device manufactured by a metrology company. This means the software is easy to use, provides powerful dimensioning tools, and correlates with your CMM. Did I mention they fit on a desk?

What do I like?
What I like is simple… Everything! I know it sounds cheesy but I am proud of the equipment I represent and I am excited for the future of our product lines. Do you make basic parts or are you on a budget? Then choose (or “go for”) an XO. If you make defense/aerospace parts, a LH is perfect. If your turbine blades and blisks need quick measurements, then the CORE is the solution! Do you want the fastest and most robust CMM in the world? The LH with a 500mm/sec scanning REVO head is the answer. No matter what your measurement task, chances are we have a solution. You just need to ask.

If you would like more information regarding Wenzel, please call 248-295-4300 and ask for a sales person. You will be directed to your personal representative.

Are We There Yet?

Development. A concept crucial to the success of individuals and companies alike. Personal development is something we should all be striving for as we go through life. 

Schooling, training, job opportunities, travel, the list goes on and on. As a company that is committed to the future, Wenzel has teams all over the globe whose sole purpose is cutting edge product development. 

As you may know by now, we have recently released new versions for both of our Metrology software, OpenDMIS 6.5 and Quartis R15. 

Both these releases have added important new functionality, and robustness to the previously available products. One of the crucial benefits to you, the customer, when considering a company like Wenzel - is our ability and willingness to listen to customer feedback and apply it to our software. 

One example of our short development chain involves a customer who had experienced a problem scanning parts with a PH-6 (which isn’t typically used in scanning applications) due to limited software function and support for that specific probe type. 

With a few emails to the development team, we were able to ensure that full PH-6 support was included in the next software release - only taking a few short months to complete. 

Occasionally we are able to provide patch updates (depending on software and issue) even quicker. This kind of ability to affect change for our customers is generally unheard of in the industry. 

The development cycle, while unique to each software, has been designed with the customer and their requirements in mind. So what are some of the improvements?

An update for both software is the increased support and compatibility for very large CAD files using an optional 64 bit version of the software. 

The Quartis R15 CAD Interface has also been updated to support:

- Inventor (V11 to 2017) 
- Parasolid (10 to 29)
- Solid Edge (18 to ST9)
- SolidWorks (2003 to 2016) - 2015 and higher only available in Metrosoft QUARTIS (64-Bit)

The update to Quartis R15 has added support for peripherals  such as  the FARO arm, a CNC rotary table, and the Renishaw PH10-iQ, as well as a unified ribbon interface for the construction of elements - even giving a live preview in the graphics area. 

For the exhaustive  list of updates to R15, visit -

OpenDMIS 6.5 has added some enhancements such as  Point Cloud Inspection (written about here by Patrick L. additional support for Dual Arm machines, many productivity enhancements (DRF tolerancing, Euler angles, feature/datuming tools, and debugging tools) and the capability for Group Point Measurement.

Group Point Measurement, is a unique function that allows for a more efficient communication between the Software and Controller. Points can be processed in large batches, rather than individually, which can dramatically decrease cycle time. 

Group Point Measurement can be applied  to 2 or more points, can be used with 5-axis measurement on REVO, or PH20 and supports all program search functions. For more  information, or a copy of the  OpenDMIS 6.5 release notes.
