  • TP20 non inhibited

    Have a TP20 stnd force. We will call it old body(part that has threads) and old mod(part that mags to body).

    We got a new TP20 body is the non inhibit style(not affected by magnetism along with some new modules(stnd)

    I measure 1 part 5 times with old body old mod and get results. I change only the module to a new one and get similar results. I change to the new body and new module and I am getting @ 0.003" difference in numbers.

    I do not even move the part once it is in there. The only difference is the old body does not have non-inhibit properties and the new one does.

    After each change of probe components I am calibrating and the results of calibration are fine.

    Any help is appreciated. I have to move onto other parts, but will need to come back to this problem very soon so I will be looking for some direction. Thanks!!!

    1) Do you re-align the part when you change over?
    2) Did you tell Pcdmis that the qual-tool moved or not? If you told it that it moved, then you have NO relationship from old to new and you MUST realign the part

    I would guess that the new body is just a touch (0.003") different in length than the old one.

      yes I re-align and yes I say the tool moved and the program has an alignment in itself that is run and the feature is a distance but not in Z direction.

          What type of feature are you measuring? Are you measuring the distance between two circles? Are you measuring the diameter of a circle?

            I'll repost it here, have you tried measuring known standards? Gage blocks, ring gages etc.? That will show which is incorrect.
            When in doubt, post code. A second set of eyes might see something you missed.

              Is there any magnetism in your part or master ball?

                demaged all items

                also ran test with sphere for all 3 scenarios and the sphere measured good for all three(a repeat prgm made)

                feature measuring is a notch depth but not in z direction

                  I would do as John suggested. Measure a gage block and measure a ring gage. I would also proceed as follows. Use the same length and size tip on both modules.

                  Install old TP20 with old module.
                  Calibrate answering "yes" to the sphere moving
                  say OK and get out of probe utilities window.
                  F9 back into probe utilities window
                  calibrate answering "no" to the sphere moving
                  Measure features

                  Install new module on Old TP20
                  calibrate answering "no" to the sphere moving
                  measure

                  Install new TP20 and new module
                  calibrate answering "no" to the sphere moving
                  measure.

                  When you measure use the same program. This program should have a full 3-2-1 manual alignment, a full 3-2-1 dcc alignment and the necessary features measured

                    With all of your combinations: [edit](oops sorry Goodluck)[/edit]
                    Measure something different than the master ball. like a ring gage.
                    Measure the distance between two master balls.

                    Your not giving us all of the info. I think Matt was on right track with the part alignment(if the master ball reads "good"[whatever that means] on all three combinations.)
