Axis Summing
When using a lathe, it is often useful to align the compound axis with either the longitudinal or cross axis. The movement
from the compound must then be added to the axis with which it is aligned. To perform this addition automatically the
DRO provides an axis summing function. The function adds the compound to either one of the two axis and the result is
displayed for that axis. If the compound is not aligned with one of the two other axis and is set at a known angle, see the
section on vectoring.

2 Z=Y+Z
The 3 physical DRO axis displays are labeled as X, Y, and Z. When the DRO is installed on a lathe, the cross travel (X) will be
shown on the X axis display, the longitudinal travel (Z) will be shown on the Y axis display, and the compound travel (Z’)
will be shown on the Z axis display.
