How Did You Get Into CMM Programming?

Just as the title says - how'd you first make your stake as a CMM programmer?

For me it was when a recruiter on LinkedIn randomly reached out to me asking if I was interested in being a Metrologist for an international company while I was working as a Quality Inspector at a job shop in 2020, just before the pandemic. I knew nothing about Metrology/CMM programming until I blew the technical portion of the interview process and got hired anyway haha! Ended up being mentored by a professional for 2 years before moving onto a specialized CMM programming gig at another company in 2022.

I figured - as it seems like a lot of us got on-the-job training for CMM programming, you guys/gals must have some interesting stories to share about how you got to where you are now, as CMM programmers.

  • We also had a DEA gantry CMM with a 5 foot by 9 foot granite table. It was a manual machine that ran off a computer the size of two lockers. Didn't have a display. Everything was printed on a teletype printer. Printer was parked under the Gantry Cross beams that were only 5 1/2 feet above the floor. Lots of ******* heads. Probe was qualified using a cube shape artifact. If you wanted to change the orientation of the probe you had to disassemble and reassemble it from the mast. Orientation was limited to +X, -X, +Y, -Y and Z.


    It hadn't occurred to me that there was a time when manual gantry CMMs were used. What a lot of work that must have been to use!
