Determining the Adjustment Value

Adjustment Value for the Y-axis Origin
You determine the adjustment value from the difference in levels at the seam produced between the first and
second surfaces in two-surface cutting. The estimated adjustment value is one-half the difference in levels.
However, be careful to note the sign of the value (plus or minus). As the figure shows, the sign of the adjust-
ment value (positive or negative) changes depending on the direction of the misalignment.
As an example, when the difference in levels is 0.2 millimeters, with the upper level misaligned in the positive
direction and the lower level misaligned in the negative direction along the Y axis, then the estimated adjust-
ment value is -0.1 millimeters.

Adjustment Value for the Z-axis Origin
You determine the adjustment value from the discrepancy between the expected and actual values for the
thickness of the finished result of two-surface cutting. The estimated adjustment value is one-half the discrep-
ancy. However, be careful to note the sign of the value (plus or minus). When the actual value is larger than
the expected value, the adjustment value is negative.
As an example, if data for a height of 50 millimeters yields cutting results that are 50.1 millimeters, the estimated
adjustment value is -0.05 millimeters.
