Chapter 1: Introduction to the FaroArm
interface to the maximum level required and measure the associated
deformation (in. or mm). The torsional forces or moments at the base
are generated by using a calibrated torque wrench. The deformations
can be described as a slope (in./in. or mm/mm) and can be measured.
The deformations must not exceed the deformation reported at
certification.
In general, the excessive translation deformations are added directly to
the certified accuracy, while the excessive angular deformations of the
base affect accuracy as a more complicated trigonometric function of
the length of the reach.
