Measurement comparisons
Measurements taken with the launch unit on the bed of
the machine are equivalent to running a dial test indicator
along a ‘straight edge’ mounted to the surface of the bed.
If the launch unit is mounted
in the spindle, angular errors
can cause errors in the
straightness measurement.
XM set-up best practice
For relative measurements between the tool and the bed/component,
the launch unit must always be mounted on the bed of the machine.
The receiver must always be mounted on centreline of the spindle. At the
point measured below there is zero height variation between tool and bed,
but the XM system would show a deviation because of the rotation of the bed.
