  • Probe Calibration Routine?

    Hi. I'd like to be able to calibrate the 4 different touch probes (for all the existing rotations) that are stored in my probe rack using a single program that will be easy enough for our production people to use. I'd like to have it so they just need to take either a point or a 5-point sphere on the calibration sphere. Is this possible, and if so, how?

    Currently, I am opening up a program that has each of the probes in it, selecting the probe and calibrating all the probe rotations through the F9 probe utilities menu. I don't want to teach them how to do this, but I need a way for them to make sure that it gets done.

    Any assistance is greatly appreciated! Thank you in advance!

    Yeah, this is relatively easy to do. I created a program just to calibrate the probes in rack. That's all it does.

    All you have to do is create a new program using the Auto Calibrate Probe command. Just put the command in for every probe in your rack. Should be a piece of cake.

    Here is miine:

    Code:
    STARTUP    =ALIGNMENT/START,RECALL:,LIST=YES
                ALIGNMENT/END
                MODE/MANUAL
                FORMAT/TEXT,OPTIONS, ,HEADINGS,SYMBOLS, ;MEAS,NOM,TOL,DEV,OUTTOL, , 
                LOADPROBE/2MM
                TIP/TIP1, SHANKIJK=0, 0, 1, ANGLE=0
                DISPLAYPRECISION/5
                COMMENT/REPT,     
                COMMENT/OPER,NO,=====================================
                               ,This program is to qualify all probes
                               ,=====================================
                COMMENT/OPER,NO,Program starts with the 2mm probe.
                AUTOCALIBRATE/PROBE, PARAMETER_SET=Qualify, QUALTOOL_MOVED=YES, 
                              SHOW_SUMMARY=NO, OVERWRITE_RESULTSFILE=NO
                COMMENT/OPER,NO,Load the 1mm probe.
                LOADPROBE/1MM
                TIP/TIP1, SHANKIJK=0, 0, 1, ANGLE=0
                COMMENT/REPT,    
                AUTOCALIBRATE/PROBE, PARAMETER_SET=Qualify, QUALTOOL_MOVED=NO, 
                              SHOW_SUMMARY=NO, OVERWRITE_RESULTSFILE=NO
                COMMENT/OPER,NO,Load the Star Probe
                LOADPROBE/STAR - NEW
                TIP/TIP1, SHANKIJK=0, 0, 1, ANGLE=0
                COMMENT/REPT,     
                AUTOCALIBRATE/PROBE, PARAMETER_SET=Qualify, QUALTOOL_MOVED=NO, 
                              SHOW_SUMMARY=NO, OVERWRITE_RESULTSFILE=NO
    Note that you have to create a parameter set for each probe. Also note that for the 2mm probe, (the master probe) the qual sphere has moved, and the operator will have to take a single point on top of the sphere.

      I'm running mine right now. I turned on the Show Summary because I like reams of numbers.

      Just added:

      1) A clearplane definition after the first probe is loaded that will put any of my probes in the free airspace above the qual sphere.

      2) A clearplane move after each calibration.

      These ensure that no probe finishes with an awkward placement that could possibly mean hitting the qual sphere on it's way up to the "Mount Point" where it goes to change probes.

      For kicks I added this code too:

      It's all pattern recognition.
