alignment

QC5717
Ok so I am trying to get familiar with pcdmis 4.3 without reading the massive manuals. My shop has had a 2.0 arm and this software for quite some time without really being used much at all. our programs are written for virtual dmis and in use with old arms that no one will even calibrate anymore.

I am currently stumped as to how to make the correct cordinate alignment. I am writing offline with only prints no cad. Using datum A plane a line constructed out of Db and DC . I want to referance x and y back to DB circle with a -27.45 rotation on the x.

Can anyone please walk me through this.


Thanks in advance,
Christopher

    Hello Christopher,

    Welcome to the forum. There are a lot of knowledgeable people here who generally are happy help a new person learn. However your post begins with a statement that indicates you do not wish to put forth any more effort than is absolutely necessary. If that attitude works for you, great. But I would humbly suggest you abandon Pc-Dmis in favor of some other software that focuses on a dumbed-down-for-dummies methodology.

    Considering you might be wondering what I am going on about I provide the following translation:
    I am trying to get familiar with pcdmis 4.3 without reading the massive manuals
    =

    'I want someone to magically dump into my brain all of the knowledge they spent years, tears, and effort acquiring.'

    Rots-O-Ruck!



  • The alignment utility in 4.3 is really similar to the utility they had in 4.2. You shouldn't have many problems just diving in and going for it. Alignments really aren't that important anyway, its a manual machine so it shouldnt crash too much.
  • I guess my first measage on this forum seemed offencive sorry for coming off as a dumbed down dummy who wants to sap information out of your brain.
  • I repeat...... TRAINING.
    That said...
    Measure and/or construct each of the features you want to use in the alignment.
    Level to the plane.
    Rotate to the line.
    Origin Z to the plane.
    Origin X and Y to the circle.
    Rotate -27.45 degrees.

    There you go....

    Any further help would require more information from you....
    And probably a purchase order for the costs of either training or writing your program for you.
  • Alignments are pretty basic for cmm programming. Get training. Check the help file and see if there exists any tutorials.

    Good luck.

    Sorry you are offended we are reluctant to give you bad information. Most of us take our careers pretty seriously. We are good at what we do, but we spent years learning to get where we are. We did not just log in here one day and say, "Here I am, what do I do?"

    Pc-Dmis is a complex software. Alignments are critical in both CMM and surface plate inspection. Learning to do them properly really requires training and practice. The concepts are too abstract and the possible variations too vast for anyone to learn this via a web forum. We could easily give you a basic run through as John Kingston just did, but your part might fit a simple 3-2-1 (plane, line, point) format.

    Furthermore we have not even gotten to the black art of GD&T and how you determine which features to align to, much less how.

    Heap on top of all that the fact that you start off by saying you don't want to be bothered to attempt to train yourself by reading the manual. . . what do you expect?

    The help files actually have some pretty good basic alignment explanations. However I caution you again that if your alignment is not correct, none of your measurements will be. I will generously guess that you, like so many others, have been volunteered to "be" the CMM guy. This is not something you can learn in an afternoon, a week, or even a month. If you have arrived at this point with no GD&T, no surface plate experience, and no CMM experience, it will take months of intensive training and study to achieve a minimum level of proficiency. The salespeople won't tell you that. The management doesn't want to hear that. It is still the truth.

    Rots-O-Ruck!

    If you stick to this, after you have had some training, when you run into a wall, search this forum, you will probably find the answers you seek. If not, then post as specifically as possible, with as much info as possible, (code and drawings are often necessary), that is where and how this forum can be an invaluable resource.
  • Thanks for your time all back to the books it is when i can fit it in the work load. I do have alot of experiance with the much older software we use with our much older romer arms model 1036 and B&S bridge type machine. The 1036 arms are over due for calibration and cimcore wont calibrate them anymore i was told from the lead inspector.

    Yet no one in the department has the desire to become proficiant with the newer arm and software, which seems to be a completely differant beast than out dated virtual dmis.

    Once again thanks for taking the time to give your input to my situation.

  • Christopher,
    Read Wes' post. Now, read it again.
    Many of us here take this sheet seriously. I don't know what industry you are in, but if I am flying in a plane that your parts are on, I want it done RIGHT.
    After 17+ years in quality, I still make some assumptions. If I don't know the function of a part or have a document telling me otherwise, I assume that it is life critical. That's how I approached your post. I've dealt with Wes, Ironhoe and DPH for years. They approach this stuff the same way.
    I'd put my life in their hands, based on their skills and how they handle each situation.
    By NOT giving you what you want, they helped you more.

    Training my friend........

    Get it?

    John
