  • Don Ruggieri , has already contacted me directly. I explained what was happening.

    The difference in the reported values is due to the U modifier having a different value for each call-out. When the U modifier is invoked, we essentially shift nominal to the centre of the zone. This means that for FCFPROF3, the nominal is 0.001 further away from the CAD surface than it is for FCFPROF2. This is born out by comparing the MAX and MIN values. FCFPROF2’s min is -0.00007 whereas FCFPROF3’s MIN is -0.00107 (0.001 further from nominal). The MEAS is twice the largest deviation (as I explained for the other problem we discussed) 0.00177/2=0.000885 for FCFPROF2 & 0.00213/2=0.001065 for FCFPROF3.
