Dirty parts

Vladimir
Hello colleagues! Hope you have a great weekend and the sun is not burning around like in our region Sunglasses
In the light of recent events at our enterprise, it became interesting to me. Do you face the fact that poorly cleaned or completely contaminated parts are brought to you for measurements from production? Often, a small piece of metal adhering to a part can significantly affect the measurement results. In addition, part that is poorly cleaned from oil contaminates the probe, and microparticles adhere to it during measurement. One way or another, with a large number of measurements, I have no desire to check and clean every detail. We agreed with the production that they will do it, but last time we had to redo a large number of measurements due to poorly cleaned parts.
How does it work in your company?

  • Bwhahahahaha That's funny. Production cleaning parts. LOL. Even when they try, they have a hard time grasping how clean parts need to be for the CMM.

    Interestingly, we recently dedicated one of the CMMs for production to check every piece off the machine for a particularly problematic part. It was funny to watch them run the part and get undersize holes. I asked them if they cleaned the holes and they say, "I blew them out with air." I've seen them have to run the part 3 times before they got it clean enough to accurately measure the part. So finally there are a couple of operators that understand it, but if you haven't tried to check a part on a CMM when it's dirty, you don't really get it.

    Like you said, everywhere the probe touches is important, even if it isn't a tight tolerance, because the probe gets dirty and it affects other measurements.
    The struggle is real, my friend.
