long program run times

I just made a program that has 43 minutes run time. That's the longest I have ever done for a single part. I did a Zeiss program that was 9 hours but it was for 20 parts at the same time. What is some of your run times?
  • I suppose you all spend lots of time planning and review the probe path and such. but we are not perfect. How do you all handle unexpected probe hits and things of that nature. Or a scenario where your measurements are so far off you decide to re calibrate your probes. Do you just have to start over? Print the report in sections

    Biggest machine I have is a 7107 and the longest run time was probably about 30 mins.


    Those are some good questions... the fact that you're thinking of these things without experience tells me you're a sharp one. People finding out that my ~18hr cmm cycle run had to be re-ran made me sharp. Every program made use of the ONERROR function and NOCENTER on holes to name a few... plenty of "what if" logic too - to prevent stopping and re-starting a 2 shift CMM cycle run. These parts were huge and very detailed.


  • AstonishedAstonishedAstonishedThats cool as h3ll, would love to se epics of your machine! I am lucky, all of my stuff is 10 years old or newer (except the manual CMM from the Cold War lol)

  • Exactly why I do use them. My issue not vibration but people bumping the machine.
  • Here is one from when it was in the old, original lab here, you can see the drive rod for the Z axis, above the pressure gauge.

    Very cool! I bet that thing has paid for itself 10X over by now
  • Clearance Cube limitations with using star probes with articulating probe head.
    When the features that are being measure at the bottom of the part using Tip 5 and trying to stop the probe from moving above the part for every tip angle changes.
    Another, issue with using star probes with articulating probe head is when you switch from T5 to T3 with no probe angle changes the probe will still try to move outside of the
    clearance cube constraints.
    When you do get the probe head to staying within the clearance cube constraints you will get a warning message every time that you are changing the probe within the clearance cube.
    Then when you want to use the MINI routines you have to use the clearance cube and that is not just a click and play either.
    The other option would be to use Feature Based Measurement (FBM) in which is an add-on.
    In other words your better off doing what others have posted here to work with guiding the probe around the part for now. At least until Hexagon does some major improvements with the clearance cube.

    In other words clearance cube = garbage Slight smile
  • Funny thing, the new Global (3.5 years old now) was basically the same cost (new) as the Validator was (new) all those years ago.

    Original OEM 'specs' on the Validator: +/-0.0007". Yeah, that was how it was listed. It is much better now. Between the 3rd party cert guy and myself, we have it down to a TOTAL error of 0.0006" (was just calibrated/certifed) a few weeks ago. Between him and Rondog (other site) I have all the 'info' for the table map of the machine (ASCII file on the hard drive). When I have slack time, I use my home-made step bar & ball bar and tweak the table map a touch here, there, and save the file as a 'backup' for when the cal-tech is here. I load it up for him to use, once it is certed to that file, I use that version from until the next year. Yeah, max X error (total) is 0.0004", Y is 0.0006" and Z is 0.0002" (linear on a step gauge). Max square difference ANYWHERE on the machine (I use 29 positions) is 0.0007", XY, XZ, YX, 45 degree, etc.

    Oh, and the new Global is a foot+ wider (X), taller, and several feet longer (Y) than the Validator

    Geeze, that machine has some character! Nice!
