  • SP25 PARAMETERS ETC.

    I JUST STARTED USING THE SP25 SCANNING HEAD AND I CALIBRATED 70 WRIST ANGLES THAT TOOK 5 HOURS TO CALIBRATE. DOES ANYONE HAVE THE PARAMETERS FOR THIS PROBE ALONG WITH ANY OTHER SUGGESTIONS. THE CALIBRATION WOULD SCAN ONE WRIST ANGLE GOING AROUND AND BACK, CRISS CROSS AND BACK AT 3 PLACES AND HALF THE SPHERE, THEN IT WOULD DO THE SAME WRIST ANGLE AGAIN USING THE SAME TECHNIQUE. 5 HOURS JUST SEEMS TO LONG BUT I ALSO DON'T WANT TO LOOSE THE ACCURACY. ANY SUGGESTIONS OR COMMENTS WOULD BE APPRECIATED.

    I am just jealous that you have an sp25....( I still have to deal with the big bulky sp600) have you tried calling B&S, or do you not have the sma?
    If you do get any answers from B&S regarding specific parameters, make sure that you still do some testing to assure that they are right cause I know I had several different answers when trying to get a basic starting point for specific parameters for the sp600--trigger forces that ranged from .06 to 1.2--and the different techs I talked to knew what I was tring to do.....
    Anyways, try calling them and see what they have to say.

    Although there are alot of super gurus here, I don't know how many have the sp25--I haven't heard too much on that particular head here yet......LOL

      Im no expert on the sp25 but I believe that what you see is what you get for the calibration. If Im not mistaken the cal routine is what it is and there isnt anything you can do to get around it. Im pretty sure that the routine has improved from its first "release" but its still crazy long.

        It sounds like it is calibrating (qualifying the tip) to ISO 10360. You have to scan the artifact in at least 4 different directions along the artifact once has to be around an equator (I believe). I am not sure if ISO 10360 requires it to do it twice though so I am not sure on that one. The criss cross at 3 places then half the sphere does sound like the ISO method though. Here is the funny part Renishaw claims that tip qualification is "fast" with the SP25. I have not seen a fast tip qual with a scanning head yet but I suppose fast is probably relative. In this case relative to molases in winter.

          Hi

          If possible install 4.1. It uses a new calibration rutine - but still - yes take some time.

          Try to reduce the ph10 positions.

            I believe what you are seeing is as Craig pointed out and this is also the Renishaw prescibed method.

            Maybe fast to an SP600? or maybe as compared to a Zeiss? Who knows...

            Do you really need all of those angles?
