CMM Use In Manufacturing

Hey guys/gals I am wondering how you and your CMM are used. aside from CMM operator, what titles do you carry? many? Engineer? Programmer? Metrologist?



  • good luck! we have people set up interviews all of the time and then never respond (so they can keep their unemployment going)


    We have people responding and we are setting up interviews. Another part of my job is being a part of the interview process when hiring people for my department. I want to get a sample part and either run it or program then run it (if they are programmers) as a test. To me the programming and running is easy, it's the analyzation that can be difficult.
  • what I am trying to say is that they intentionally don't move fwd with accepting the offer so they can show movement to the unemployment dept while never having any real intention of getting the job in the first place =/
  • My current title is 'CMM Programmer'. It's a sweet gig. I program offline 95% of the time, the other 5% is on the CMMs verifying the programs I wrote for the first time. There are 2 other CMM Programmers here as well. The CMMs are operated most of the time by full time CMM Operators. We make low quantity runs of aerospace parts, so most programs will only be needed a handful of times. The only downside to this setup is that there only a few CMMs and a lot work going through them. When I write a program I need it to be right the first time, there are no opportunities to test and tweak things at the CMM.

    I have worked other places with different titles and different responsibilities in addition to CMM programming. I have worked at high volume repetitive work type places where I programmed the CMMs so that anyone in the shop could operate them to measure their parts. That worked better than I would have thought. It was lots of work to dummy-proof things and fix things here and there, but empowering the machinist to measure their own parts really improved part quality, turnaround, and interdepartmental moral.

    I have also had jobs that are full time at the CMM both programming and operating. It can be nice for learning, but unless it is at a small company I don't think it is a good way of structuring things. It can really turn an individual into a resentful bottleneck. Though, I have heard of companies that make it work by just having a surplus of both CMMs and programmers. Each programmer is basically the 'owner/operator' of an assigned machine. I imagine that system could work really well in a lot of ways, especially when growing talent. Also, it keeps things interesting. Just programming or just operating all the time can get kinda dull.

    I don't think there is one best way to structure the tasks of CMM programming and operating. It depends on the type of parts being measured, the quantity involved, how they are manufactured, lead time, etc.
  • Senior Quality Technician. Currently working for a medical device OEM. We make automated equipment that a microbiologist would use to find and identify bacteria in blood, food and drugs. One of our divisions makes a machine that test for Covid. Low volume, High mix of parts.

    Previously worked for a machine tool maker. Most of what I did was write programs for capability studies for the parts our customers wanted to run on our machines.

    Before that I worked for a air conditioner compressor maker. High volume, Low mix.

    Low volume, High mix places always keep you on your toes. Don't have much opportunity to really refine your programs the way you'd like to. On the other hand there is something new coming in all the time.

    High volume, Low mix places let you really refine your programs. Eventually they become pretty much bullet proof. You see all the ways that things can screw up and develop countermeasures. Of course once you get there, it gets kind of boring.
  • I am a CMM programmer / (backup) PPAP Coordinator. The job I was hired to do is programming and measuring any part that requires PPAP. Weather that be a design change, new part, material change etc. I then fill out customer dimensional reports and gather other required information like PFMEA, capability studies, Gage R&R's, toxicity and submit them on their respective sites. I also program parts for ongoing capability/daily checks and also I do the calibrations that require the CMM.

    The previous programmer was very inexperienced. She had one class and was expected to be the expert. She handled programming and that was it. Since I was hired salary the roles of my job have increased drastically. On top of everything listed above I have also volunteered the CMM as a problem solving tool and not just a part verification tool. So now I also help production and the engineers problem solve and I am involved in most dimensional change decisions made.

    All in all this job gives me the most job satisfaction of any job I have held previously. And at a previous job (Air Force) I had a hand in the MOAB that was dropped during the beginning of Trumps presidency so that should say how rewarding this job is.

    At my last job we made the big guidance fins for the Massive Ordinance Penetrator. All aluminum and very heavy SOBs.
  • Are you seriously asking me that question? I thought you knew me, of course mean Rolling eyes
