scratching moments at the end of the production process when it is discovered that something is wrong.” Mastering SPC software can be challenging, and point- cloud metrology tools can ease inspection tasks. “Traditionally charts have been used to represent the data being captured and still are for many applications,” said Capture 3D’s Old. “The more data acquired, the more reliable the information, but also the more difficult it is to analyze and understand that data and to then make intelli- gent decisions. This process requires a tremendous amount of expertise and time, if you ever took statistics in college, you know what I mean.” In the 3D measurement world, users can measure complete parts with millions of measurement points on each sample and then use color images of the part to show the changes occurring over time, he said. “Now management and engineers alike have a tool that they can both easily understand, communicate about and make well-informed decisions about, resolving a problem before it occurs.” Capture 3D’s software partner, GOM (Braunschweig, Germany), developed a trend package included in its ATOS and GOM professional software, Old added. “Not only does the GOM software trend numerical values, but it also pro- vides full 3D surface color mapping,” he said. “For example, we can produce a full 3D color map for Min/Max deviation, Arithmetic Mean, Range, Sigma, CP


value, PP value, CPK value and PPK values. The trend feature also can generate


an average mesh from a group of meshes or tell you the Golden Part or Mesh or the best manufactured part out of a group of parts. The ‘Golden Part, or Mesh’ is useful be- cause there are times when a working part is actually better than the originally designed part and the manufacturer can use that as a benchmark instead.”


“The geometry alone isn’t sufficient.”


Using 3D scan data for inspection completely changes the way people manufacture their parts and brings a much higher level of quality over the older tactile metrology meth- ods, Old said. “If you can imagine designing a part from the ground up and trying to fix quality issues for which you do not know the cause [root cause analysis], using a tactile measurement machine is like throwing darts at the part hop- ing you hit the problem area,” he said. “Lots of iterations and rework. With the ATOS Triple Scan, it is like shooting the part with a shotgun to find the problem. You see it all at once and

Here's part of an email from


another satisfied customer: "This is awesome. I'm very happy thus far! Based on the information coming in, I can set parameters to control our processes prior to an out of tolerance event. All this based on the capabilities of the machine and probe. The best part yet is, it's ALL automated. Thank you again for ALL your support."

you can find the issues much quicker with a higher level of certainty. Fewer iterations and quicker times to market. Once the part is ready for full production, manufacturers are using the ATOS Scanner in tandem with the SPC software to help monitor their processes.”
