The team here at Third Dimension have just returned from this year's EPMC where we enjoyed sharing, learning and discussing all things dimensional metrology.  We've been active and vocal supporters of EPMC (and its predecessor LVMC) since its inception.  As a member of the organising committee I’m especially passionate about knowledge sharing opportunities.  What makes EPMC different is that, like CMSC in the USA, it's a non profit event that is organised and planned by members of the metrology community that volunteer their time to create an event that promotes all of our shared goals. 

This year's event had some exciting new features including the metrology stadium as well as dual presentation tracks.  We presented a talk on one of our particular areas of interest - making better use of measurement data to improve processes.

Always popular too are the ample networking opportunities including the always popular evening receptions.  (I've got some pics of Jas there that could go here if I haven't copied them over).  There really are few events as unique as this to allow people to discuss current learnings along with the challenges they face on a day to day basis with their peers from a wide variety of organisations within the industry.  If you haven't been to an event like this before, I highly recommend it.  There are few networking and learning opportunities out there that can make as good a use of two days as this.

GapGun systems ship with one of two types of sensor heads - U or M series. It sometimes isn't obvious which to select, or what their advantages are, so this article explains both the differences and their advantages when compared to other systems on the market.

The two types of GapGun sensor are

  •  DSC3323PSwebU-series Universal Sensors for use in general applications from bright white surfaces to the very darkest automotive paints on the market - paints which competing sensors cannot measure.
  • M-series Reflective or metallic sensors for use in specific applications where highly reflective materials are commonly encountered - such as bright machined metal (turbine components) or chrome.

GapGun U and M series sensors achieve this wide range of surface capability using a threefold approach

The GapGun2 was our second generation system, launched in 2002 and used worldwide for a wide variety of aerospace, automotive and dashboard applications. GapGun2 was also the smallest and lightest system we ever made.

Superseded by the fully mobile and wifi enabled GapGun MX+ and GapGun3, the GapGun2 quietly bowed out in 2004. We are proud to say that all GapGun2 users are now upgraded to GapGun3.

Although in many respects the original GapGun was quite similar to today's production GapGun3, its approach to the inspection task was entirely different.
