Calibration

Hi, So when calibrating probe it is like I'm 10mm off.I calibrate my probe at A0,B0 ok but then it moves to A90,B-90 its hitting the calibration sphere.So I tried to start again manul first touch but still happened. I then tried did manul touch A90,B-90 but when it went to do the A0,B0 it was off by about 10mm.Please any thoughts

  • Put something pointy on the CMM Plate.

    Position the stylus, by eye, directly above the point at A0 B0 (or A90 B0 if you want even better).

    Lock the X axis on the jog box.

    Spin the head to A90 B-180 (or +180 if that is your thing).

    Using ONLY Y and Z, move the stylus directly over the pointy thing.

    If the stylus can't get over the point with Y and Z moves (meaning you see an X error), the head is rotated some amount.

    If it is off far enough, you can adjust it, or you can call Hexagon to adjust it.

    Loosen off the quill, correct, tighten. Don't strip threads over-tightening. Don't leave it loose so it moves over time on its own.

    FYI - It doesn't have to be perfect. It doesn't even have to be close enough to qualify a stylus WITHOUT you doing a manual qual first, it needs to be close enough that when you insert it into a hole you don't shank.
    If you are doing sheet metal, it can be off ten degrees, it won't matter.
    If you are like me and slide a 2mm stylus on a 1.5mm shank 3 1/2" down into a .125" diameter hole, it needs to be fairly close.

    Point of that is, don't make a problem where there really isn't a problem. It can be off and have zero effect on your results. The qualifying is what affects your results.
