F or example, the GOM ATOS Triple Scan — which is capable of measuring up to 8 million points per scan — won the GE High Accuracy, High Throughput Inspection Tech- nologies Challenge where the objective was to inspect the blade of a Victorinox paring knife in under three minutes. Accuracy of the inspec- tion had to be 10 microns or less with a repeat- ability of five microns. Despite the competition from 50 other entrants, with its advanced blue light technology the ATOS Triple Scan was able to come out of the competition a winner. 1 Let’s pause here and talk about “blue light” because that term keeps popping up. Not all light-based scanning systems use blue light. Some other systems use white light. Capture 3D’s ATOS 3D scanning systems use blue light because the wavelength of blue light is narrower and allows for better filtering against interfer- ence from ambient light. Why is any of this important? So why is all that you’ve read so far important? Because typi- cally, in manufacturing, increasing speed can come with the risk of decreasing accuracy. But implementing a Capture 3D’s ATOS automated robotic ScanBox gives you the ability to dramatically increase speed without sacrificing any accuracy. In fact, in some cases the accuracy offered by an ATOS system may exceed your old CMM. This translates to more parts made, in less time, with fewer wasted materials, and more money saved. So why isn’t everyone using it? “The biggest objection we face is, by far, the ‘this is how we’ve always done it’ mentality,” Staton tells me, and went on to explain that “…CMM’s are great. They’re accu- rate, but they’re slow. 54 NORTHWEST AEROSPACE NEWS There are some applications for which that’s fine but for a manufacturer that’s a job shop, or doing one- offs and first articles, having the ability to use ATOS and knock out a scan and a measurement in a time that can’t even be seen, much less programmed, by a CMM is invaluable.” Staton further offered a use-case from Capture 3D’s website. “We have a use case on how one of our aviation and defense customers adopted blue light scanners as a standard, and on one project the time savings alone saved up to 100 million dollars.”
