  • PC-DMIS 2013 - Student Trying to learn

    Hello,

    I am a student who has been tasked with learning how to operate the CMM in the lab I work in. It has not been used in years, and the last person to operate it graduated 4+ years ago. I have created a program but when I go to automate it I get a machine error TR_PRB01, no probing within Probelimit. This occurs whenever the probe attempts to move down from its home position.

    It is running pc-dmis 2013 and is a brown & sharpe ONE 7.7.5 with a renishaw PH10T probe

    Please Help!

    Training training training. Get sent out for training!

    You are getting that error because the area the CMM needs to measure is outside it's limits. That part is floating in CMM "space". You will either need to create a readpoint alignment or manual alignment to "tell" the machine where the part is on the table. Once it knows the location, then it can automatically measure the part. Word of warning: Make sure your alignment is setup correctly. If not, you can cause some bad things to happen.

    By the way, in what atmosphere is the CMM in? You say a lab. Is this a work environment or school environment?

      Look here, there are some posts about this error (or type TR_PRB01 in advanced search)

      And tell us what probe you use (the part between the PH10 and the tip !)

        So this error means that you have instructed the CMM to move outside of its volumetric extents.
        the program you are making... do you have a CAD model imported?
        If so: here is the most basic and easiest way to get you up and running...

        Create a new routine. Select the probe you wish to use. Import your CAD model.
        Visualize how you plan to place the sample part on the CMM.
        --It's not necessary, but it surely helps: familiarize yourself with X being left-right direction travel, Y being close-far travel and Z being up/down on the CMM.
        --Press F5, go to Part/Machine tab. Manipulate the three 'Part Setup' CAD toggle buttons to have XYZ match how the part will be placed on the machine.

        Now back to necessary stuff. You are going to create a 3/2/1 alignment relative to the CAD model.
        Click the button that looks like a probe tip (gray shaft with red ball) or press CTL + F4 to start "Program mode"
        On the screen, left click three points on a top surface of whatever portion of CAD is pointing up with part on machine. Press "END" on keyboard. Boom you created your 3pt level plane.
        Click two points along one front or left side edges of the CAD, closest to you first, then farther to you (or left first then right). Press "END" on keyboard. Boom you created your 2pt rotate line
        Click one point on the adjacent left or front side edge of the CAD. anywhere. Press END one more time. Boom you created your 1 point origin.
        now, press CTL+ALT+A to pop up the alignment tool.
        Level first rotate second and origin third is the fundamental method to control all 6 degrees of freedom.
        Level Z+ to your plane
        Rotate X+ or Y+ to your line about Z+
        Origin Z to your plane
        Origin X to your line or point
        Origin Y to your line or point (whichever one you didn't use above).
        Click OK.

        Now, in the edit window (where you see all the text) make sure cursor is at end of routine.
        type "MODE" press tab, type DCC, press tab.
        press enter.
        type in "CLEARP", press tab, confirm ZPLUS press tab, type number "2" press tab, confirm ZPLUS, press tab, type in 2 again press tab, press F8 to toggle OFF to ON.
        Ok, that should be enough to get you started.

        Execute routine by pressing CTL+Q or the green "Play" button.

        Machine is looking for you to physically probe the same points you clicked on CAD.
        Take 3 hits on same top surface you poked on the CAD, click on the "DONE" button on the jogbox.
        Take 2 hits on the same edge you probed on CAD. Click the "DONE" button on the jogbox.
        take 1 hit close to the same spot you probed on CAD. Click DONE (or enter button, or mouse-click continue on the pop-up) one last time.
        DCC (Direct computer control) will take over, and execute a clearplane, moving the probe up 2".
        routine will finish now.

        From here on out, you should be set to use autofeatures and the clearplanes will automatically be produced.
        have fun!

          +1 let me know if you're close to San Diego. I was a broke student once, now I'm just broke but I'd be willing to help out.
