6. For Z squareness to X and
Y, the Machine Tool
Geometry program
subtracts the Best-Fit
slope of Z from the Best-
Fit slopes of Y and X and
calculates the squareness.
Therefore, the result for
the squareness of Z to X is
.0002 in/ft, which means
the Z-Axis is tilting to the
left.
7. The squareness of Z to Y
is .0004 in/ft, which means
the Z-Axis is sloping up
relative to Y.
