  • Good or Bad

    I inspected a part in 4.2 and do not know if it is good or bad. I need some help.

    I have two bores. One is Datum and the other is on the same centerline (X and Y of 0)

    I get the following three values:

    4.2 Reporting No Fit To Datums
    0.611

    4.2 Reporting With Fit To Datums
    0.081

    4.2 Reporting using Legacy Dimensions
    0.438

    My tolerance is 0.5
    Is this part good or bad?

        I see I left MMC on for the Legacy One but either way, it still gives a diff value.

              The legacy Dimension is the feature in 4.2 where you report things as were done in previous versions of PC DMIS such as 3.7

                I thought it was just the old format?

                    My first thought would be to measure the feature on a surface plate if possible and determine which is correct from that.

                      Thanks, I know what legacy means, but was not sure if BS did
                      I thought thats what they meant

                        Unfortunately, it isn't that easy. I am looking at what we call a tube. It is the Connection for a Coolant Fitting on the End of a Tank. D is recessed inside the edge of the tube by 3mm and is a 'ledge' of about 2mm width allthe way around. E is the inner Bore (76.1mm). It is located at a depth of 22mm to 30mm from the D Datum.
                        The Bore I am reporting is the Outer Bore and is only about 2mm good surface to capture.

                        I don't have the equipment to do this in a plate.

                          I beleive the .438 is correct based on the axes deviations from nominal, good part.

                            When all else fails, simply align the the require datums and do a DIM-LOCATION to see the axial deviaitons. Then do the TP and see if the axial deviations match, THEN turn on the PERP to CL and see what the TP dev is, and go on from there. You should then be able to figure out which is correct.

                              Can we see the feature control frame for the callout?
