  CNC West - What are you most excited about seeing here at Westec and what excites you most in your own booth?
Todd Johnson - It is great to be back at a show for sure. So much has changed since the last time we were here, but it is exciting to see and talk to people again. By the looks of it hand held scanners are pretty popular this year. And walking around you see a lot of the larger booths are geared towards quality. No surprise since quality has been important since the dawn of time, but we are seeing a lot of new tech to speed up the processes. I feel PMI is where the industry is headed in the future. Basically, PMI is embedding things like the GD&T directly into the CAD model. All the dimensions are part of the CAD model, but PMI isnt just limited to GD&T. Lots of different data can be part of the PMI from surface finishes to proprietary/legal notices and material specs. So if we are just talking about having the GD&T as the PMI, all the information associated with a print is now embedded. By embedding the GD&T into the CAD model the programming is 80% done when you

bring it. Boeing and all the big aerospace companies are already pushing this and even smaller shops are having to adapt. This is a huge time saver. Something that might have taken you 4 hours to program before can be done in half hour or so.
The other wave of tech is CT scanning. Lawrence Stricklan is the CT manager for Zeiss and can explain it a little. “The ZEISS METROTOM 1 is basically an x-ray machine that can measure your part inside and out without tearing it apart,” explains Lawrence. “In the old days if we wanted to measure your phone we would have to tear it apart to do so. That sometimes could actually destroy details you were trying to find out. With the METROTOM 1 you basically put the part in the machine and it will scan it with an x-ray and you can measure the components that you want to.” “This is the way the future is heading in my opinion,” continues Todd. “This technology is still in its infancy, but 10 years from now we will see a lot of this technology. The METROTOM 1 takes up very little space in the QC lab, is easy to use and is precise.”
