Offline to online alignment frustrations

kfizzle33
Hi all,
So basically I am new to the whole cmm industry but i have spent a great deal of time trying to figure this out. We just acquired an offline license for programming our parts. We have never done this before and I can not figure out how to get my offline alignment to match the machines coordinates. I know you will probably say this has been answered but trust me I have read almost everything and was wondering if someone could give me a DETAILED description on how to do this.
Thanks,
Kevin
  • So that is what i did. Went to the machine. Took an alignment using the cad file. Did an offline alignment on my part....Still not working....What am i doing! I am probably forgetting something stupid so maybe this will help....

  • Just do this.... program all the stuff you want to check and ONLY the stuff you want to check (dimensions and all the rest). Then, when you get time/part/fixture/whatever and go to the CMM, simply ADD the alignment at the beginning of the program and there ya go! Make sure you have a copy of the program so when you click on "YES, UPDATE FEATURES TO NEW ALIGNMENT" and it screws up the entire program, you have a copy you can go back to. Of course, you SHOULD click on "NO, DO NOT UPDATE TO NEW ALIGNMENT", but even when you do, once in a while, Pcdmis will update ANYWAY, so keep a backup.
  • Stop doing that!
    The part on the machine has no relationship to the part in CAD.
    Do the entire part offline.
    MANUAL 3-2-1
    DCC 3-2-1
    DCC alignment.
    THEN
    Go to the machine.
    I did stop doing that. That was what i did before i took your advice.
  • I took a look at your code. Do you start the program on DCC mode? I don't see the manual alignment.

    Thanks for that trip down memory lane, Matt. I got kicked in the f@nny by that before as I watched the the tsunami of pretty colored bars parade north to south, laying waste to the entire program.......... so nowadays I'd like to think:
    "LESSON LEARNED"

    (off topic: this forum actually still censors benign words for butt?)
  • Even Experienced programmers run into these kind of problems. Have you ever heard of the right hand thumb rule?
  • Thanks for all the help guys...turns out we had a little calibration issue....thought i was doing everything right and i was.
