Description:
Position Shift measures the static location of the spindle at different spindle speeds. The total
shift for each axis is the Maximum-Minimum of the values charted for that axis. The Combined
Shift for the machine is the square root of the sum of squares of the individual Shift values:
X² + Y² + Z² . Note that the Combined value is always larger than any individual value.
Purpose:
Large position shifts between speeds indicate significant bearing wear or a lack of stiffness in the
machine.
