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
  • When you import the model (offline mode), rotate the cad (3D rotate) on the screen until it matches the way its going to be resting on the machine.
    Then press F5 and select Part/Machine tab and set the Cad to machine axis.
  • how do you set the cad to the machine axis????
  • If noone else is going to say this I will.
    This forum is not a training tool for people with no cmm experience.
    Please search the forum for advice on how to do this.
    Before you ever think about using an offline system do the work manually on the cmm so you can see how all this works.
    Or GET SOME TRAINING.
    You dont know the basics and we cant help with that.
  • I do know the basics (just the basics). I can write the entire program. All i can not figure out is how to get the offline alignment set up. From what i have gathered from the forum... I import my cad , use transform to position it right, the just offset the machine axis under f5? I dont know if this is correct though. Because when i go to put it online it usually goes to the middle of no where
  • I understand how to take my datum create an alignment etc, just can't figure out how to make it work online

    Generally (and very simplified example) a program consists of

    MANUAL ALIGNMENT
    measured plane
    measure line
    measured point
    Align command
    DCC
    CLEARANCE PLANE
    DCC ALIGNMENT
    measured plane
    measured line
    measured point
    Alignment command
    ACTUAL INSPECTION PROGRAM
    Measured Feature
    Dimension of Measured feature
    Measured Feature
    Dimension of Measured feature
    Measured Feature
    Dimension of Measured feature


    This is only one dozens (if nto hundreds) of ways to write a program. Not only must you write it, but you must execute it on the machine. Do you recognize this structure?

    As I said in another post, let's get the (paraphrased) "basic" stuff out of the way first. . . .

    ps I tried to use spaces as indents to define the structure of the program, but they are removed when I actually post, so now I made the section headers in BOLD
  • So i import my iges file. I create my plane a line then two points. I construct a point where i want it. Then create an alignment using the plane line and new point where i want my origin

    Yes, that's a start, in programming the alignment.

    A key factor here though, you also have to execute those commands on the machine, or it means nothing. . .
  • See i can go to the machine with the part.. take physical hits using the cad model online. Then go upstairs and program it offline. The problems lies in the fact we are not really fixturing these. They will be placed on magnets on our subplate, but without having a fixture for the part it is always a little off. So to compensate for this my supervisor suggested trying a secondary alignment on the part so the cmm will see EXACTLY where it is, because we are measuring rather small parts with slots that are tiny. Is this correct and I can paste the code if you would like. I really appreciate all the help
