  • Calibration sphere missing with new update.

    We recently switched from 2013 PC-DMIS TO 2017 R1 and have lost the calibration sphere data. I'm just an operator and have no idea where to start. Can someone point me in the right direction or at least tell me what we have.

    Thanks,

    Have you ever set up a calibration sphere before? Do you have access to the programs?

      Can you add the sphere?

      Open the probe utilities dialog
      Select a probe and click measure
      On the bottom left corner, select ADD TOOL...
      Then enter a name for the sphere, type, and shank vector IJK, and the diameter of the ball.
      Select OK when you are done,

      When you are ready to calibrate, select the tool you just made.

        I do have access to the programs but I have never set one up. I don't know how to figure out the vectors

          Do you have edit access? Can you create programs?

          Ok, "I" is first, "J" is second and "K" is last, IJK

          0,0,1 is Z+ which is straight up

          1,0,0 is X+ which is straight to the right

          -1,0,0 is X- which is straight to the left

          0,1,0 is Y+ which is straight to the back

          0,-1,0 os Y- which is straight to the front


          Your pic has an angle, which way is it usually facing? Leaning away form you, towards you, to the left, or to the right?

            Would you say its at a 45 degree angle?

              The ball is facing y- in the back

                  Does size of the sphere have anything to do with these numbers or is it universal?

                    These numbers describe the direction of the shank. Yes they are universal and has nothing to do with the sphere size.

                  Yes the diameter of the sphere is important. Name the sphere and enter in the diameter.

                  Your sphere is facing in the Y- direction. If is was straight at you it would be 0, -1, 0. Since there is an angle of 45 degrees, the shank IJK values, you are going to enter 0, -0.7071, 0.7071.

                  FYI, I had to review my notes. Calibrate in slow speed just to make sure there are no crashes and then re calibrate at normal speed.

                    If memory serves me right, I think that's 30°....IJK: 0, -.866, .5 from memory so double check my #s

                      Worst case scenario, unscrew it from that base and stick in the granite straight up at Z+ 0,0,1.

                      Once you calibrated all your probes, just move the sphere out of the way.

                        edboy707 , there is also a free elearning course that will show up to setup probes and sphere and enter their vectors.

                        Login or resister at http://www.hexagonmetrologyu.com/ and search for (11100-00-30) PC-DMIS Probe Calibration Fundamentals. It looks like its been updated since the last time I viewed it.

                            It was 30 degrees lol I input the info and it worked like a charm. Thanks guys i really appreciate the help and will still be doing the Probe Calibration Fundamentals course hahaha

                            Thanks,
