deflection could contact the part, in this case the top of a
small bore, before completing deflection. Multisensor
measurement systems combine the strengths of two or more sensor
technologies on a single inspection platform so that all
critical features of a complex part can be measured. These
systems often include non-contact sensors—video and/or laser—for
surface and edge measurements, and touch-trigger probes to reach
part features that the non-contact devices can't access, such as
cross holes. In some cases, the size of a typical touch-trigger
probe may prohibit the measurement of very small slots, holes,
grooves or bore draft angles, for example. The touch-trigger
measurement technique may also prevent such measurements.
Because the probe must deflect in order to register a position,
it is possible that the probe's shank could contact the part
before completing this deflection (this is known as shanking
error). SmartScope multisensor measurem
