The process of reverse engineering was at one time an arduous task for product development; however, thanks to 3D measurement technology by FARO, the process is becoming more efficient and cost-effective than ever before. A 55-minute webinar, “Using Metrology Software to Capture Data for Reverse Engineering,” addresses the growing influence in the technology field, uses […]
FARO announced today the release of the all-new FARO® Laser Line Probe HD. The power of the new high-definition 3D scanner combined with the flexibility of the FARO Edge measuring arm creates the world’s most affordable, high performance contact/non-contact portable measurement system on the market – the FARO Edge ScanArm HD.
So what do you do when you have about 20 violins from the 1730’s show up in town? Attempt to find out why these particular instruments sound so much better than others of course. Over the years and currently, many are still trying to find that answer as to why some sound so much better than others when the apparent construction is virtually the same.
Is it possible to utilize extreme data capture while maintaining the accuracy of laser trackers? The first question before addressing the first one is, ‘why would you want to do this’?
Let’s look at laser trackers. You may already know the importance of these great tools. Critical dimensions of important features require extreme accuracy. Dimensions such as concentricity, parallelism, and true position are a few of the GD&T functions that require tight tolerances and can be difficult, as well as time consuming, to measure manually. These may be some of the most complicated aspects.
For this theoretical experiment, I find the deviation of the center point of a spherical probe by adding conductive heat through hand contact. If you want to perform this test, you will require an infrared thermometer to monitor temperature changes, a stopwatch to track time, and a FaroArm with available standard ball probes.
First, let’s review the set up for the experiment. At stability, which is achieved once the FaroArm/ probe reach the stable operating temperature, you want to perform a probe qualification and ensure that it is within spec. After wards, one must perform a DRO to a measured plane while system is still stable (before you add conductive heat). Moving the probe around the measured plane should yield a deviation no greater than your qualification accuracy. If this is the case, then you have a valid plane/qualification.
