I have an angled brackets. Two holes on each surface, angle is at 125°. Datum A is a plane, Datum B is a hole through Datum A, which is perpendicular to A. There is a hole on a 125° angled surface in line with Datum B in the X axis. Datum C is a line created between Datum B and the angled hole. Part is positioned parallel to the Y-axis on the CMM. When I apply the MMB to Datum B, the position gets worse than if I measure it against it's physical Y & Z locations. Why would the datum shift move the two holes closer together (see shift of -0.379 in Y). How is this possible?
