Notes:
Two planes were measured, one representing the lower base
and one on top of the gage block, The lower base plane was
used to establish the XY PCS Base Plane for both PCS 1 and
2. The top plane had an AZ/X of 89.9943° and the AY/Z was
90.0000°. The intersection with the pierce point with the
PCS1 Z-Axis, d1, is reported at 1.9999". The reported pierce
point on the Z-axis of PCS2, d2 is 1.9995". By not having
PCS localized to the actual measured surfaces we introduced
0.0004", d3, error!
