How Did You Get Into CMM Programming?

ALousyUser
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.

  • It was a joy.... It was a mid to late 70's model cmm. Used paper tape if you wanted to write a program in Fortran. Very few programs were written. Had a couple of hand boxes where you spun dials to tell it to measure the various feature types and do alignments. Measurement results were printed on the teletype as soon as you finished the feature. You were hanging from some handles to move the machine in X and Y. Luckily there was a roller you could spin to move the machine rapidly in Y. Had this nasty habit of dying on the last feature you wanted to measure. Constantly banging your head against the gantry. It was originally bought to measure hole locations on a tank mounted TOW missile launcher that took up most of the volume. It was however much faster than trying to layout that launcher by hand and it was a lot of work. It was pretty much state of the art at the time. Guys who were originally trained on it thought it was by far the better system while the Cordax guys thought the opposite.
