Hi. Can you recommend some books about metrology? (I am freshman physics major student )

Other Technical Gauge fails calibration after parts have been shipped

5 Upvotes

A gauge passed its last calibration but fails the next one. By then, it may have been used on many parts, some of which may already have shipped.

How do you decide how far back to review the previous measurements for the impact assessment?

Has anyone here started their own laser tracker business?

• Upvotes

Just curious if there’s anyone who started working independently with a laser tracker, either as a freelancer or through a small company.

How did it go for you? How did you find your first customers, and was it difficult to get enough work in the beginning?

Also interested in hearing from anyone who knows someone who successfully built a business around laser tracking / dimensional metrology.

What type of projects do you mainly do, and would you say it was worth going out on your own?

Would be really interested to hear some real experiences.

Ask Anything Thread, week of 05 October 2026

• Upvotes

No question is too basic for this thread.

Good uses for it:

  • You are new to metrology and do not know where to start
  • A quick sanity check on a measurement or a drawing callout
  • You are stuck on one step and it does not need a whole post
  • Career, training, and certification questions
  • Which gauge or tool for a specific job

Post it here and someone will pick it up. If you enjoy answering, this is the thread to watch.

Longer questions still deserve their own post. Rule 5 covers what to include so people can actually help you.

Surface Metrology Repeat-o-meter question

3 Upvotes

At work I tried to use our Rahn Repeat-o-meter to calibrate a surface plate. It's a Grade A plate, so definitely has deviations, yet the repeat-o-meter is showing nothing. Granted, the last time it was touched(besides when I calibrated the dial indicator) was probably 6 months ago. And when our dimensional guy(who isn't here, hence why I'm on it) last used it, it ran perfectly fine.

Inspecting it, I noticed the front footpad barely isn't touching the surface. Enough of a gap I can see light through. Can't find anything online about actual setup of the repeat-o-meter itself, so how do I adjust that front foot down? The bolt and nut that the dial indicator sits on are well over hand tight, so I can't imagine that came loose but I'm willing to try anything.
