PC DMIS Offline programming for Romer

BMONEY
PC-Dmis Cad 4.3 MR1

I know this part of the forum is for CMM but there is only one person on the portable forum so I dont think I would get much help there.
I want to write a program offline for our new Romer arm. I only have PC Dmis Cad 4.3 on my computer. We have PC Dmis Portable on the computer where the arm is located. So basically what I think I need to do is get the Probe files for the arm from the pc that runs the portable software and put those files on my pc at my desk. That way I won’t get errors when I try to right a program offline. I will be able to call up the Romer probe offline. Can this be done, or do I need to install the Portable software on my pc? If it can be done can anyone tell me how to do it?

    We have only just had a Romer arm demo & after witnessing the choreography in action we got to quiz him about compatibility with our Cmm computer & software & programs already written.

    “Whatever program you write on each will be compatible with the other”. That is what the man said. This is dependant on both Cmm & Romer having same version (ish) of software which sounds like your case.

    The only difference, a program off the Romer will need probes adding to run on the Cmm & one written on the Cmm will need the probes & move points etc stripped out.

    From the demo itself it looked to be quicker to write the program with the arm itself than to sit down & do it offline. For instance we collared an unfortunate worker strolling by & under ‘step by step’ instruction he had the Romer & test piece & CAD model aligned & measuring in about 26secs. Not bad for a 1st time effort.
  • We have a Romer arm and CMM's all running ver4.2 MR1 Cad ++
    We have programmed the arm using the CMM installs and just changed the probes when copied to the arm.

    All works fine.
  • You're right about being told that you can write a program for the cmm and then run it on the arm, I was told the same thing. And it is faster to do it at the arm instead of offline. However when I did write a program offline I didn’t have the hard probe file. So I was getting an error when running the animation. What I ended up doing was writing a quick program at the arm and then I opened that program offline at my desk and I was able to configure and save the hard probe.
  • We just got a new Absolute Romer Arm and need to determine if we can program offline. Does anybody out there know how to tell?
  • Do you have an offline seat?
    If you do you can program offline as much as you want.
    If you dont you cant.
    You have to use the offline version on the romer pc.
    (When you open or create a new program make sure you select offline as the interface.)
  • I program offline for the romer all the time, I did just what you said you've wanted to do. I put a copy of my romer probes on my offline seat and just call them up and program the part. when I call the program up in the arm I don't have any problems.
  • Just a point of note for everyone to be aware of. Although your programs can interchange between the bridge CMM and the Romer, and work rather excellently, if you plan to scan a part within an existing program with your laser scanner to get auto features - it will not work. The contact parameters for a laser are different than that of the probes, so obviously, when it comes time for the auto features to be executed in your program you will get an onslaught of error dialogs. Certainly sucks, but, I haven't seen any way around it just yet. Just thought I'd throw that out there though in case someone were to find themselves in a big company demo situation like myself and get hammered later by your boss because the holy grail wasn't able to do what was advertised. Even though this was never advertised, you know what the bosses hear when attending demos. So, just thought I would try to help prevent someone else from getting sacrificed should the situation arise.

    Since you seem to know..... is there any issue in doing contact measurements for alignments (either planes/lines/circles or tooling balls) then doing laser scanning later in the program? We are looking at the Absolute arm, 7 Axis, SI for doing RE work. Currently I am making a 'master plate' that any and all details will go on (it will also work for 2-D RE on the CMM), and the plate itself will be aligned (dowels are in the plate, detail sits on the dowels), then laser scanning the form.
  • There aren't any issues in doing that at all Matt. In fact, that is the way I prefer to do it on my parts just because I'm not a big fan of letting PC-DMIS align itself using my pointcloud. I do it when I have to, but, I prefer doing my contact measurements first to be sure I'm at least using my datums.

    Just a side note for you, if you're planning to use the scanner for RE for model creation or use in any other CAD environment, PC-DMIS cannot export a good pointcloud for use in something like Rapidform or Geomagic. We are actually finding this out here now, that on top of the third party pointcloud manipulation software we expected to purchase, we also have to purchase an additional plugin for collection of the data from our scanner. For some reason, pointclouds exported from PC-DMIS show up missing huge chunks of data when imported into any of the reverse engineering packages. So, just so your company isn't caught off guard, PC-DMIS is only useful for inspection purposes where the pointcloud is concerned.
