Abstract : The measurement of features from the micro- and
precision manufacturing industries requires low uncertainties and
nano-scale resolution. These are best delivered through ultra precise
co-ordinate measuring machines (CMMs). However, current CMMs are often
restricted by the relatively large and insensitive probes used. This
paper focuses on the assembly challenges of a novel micro- CMM probe.
The probe is comprised of a 70 μm glass sphere, attached to a solid
tungsten-carbide shaft of diameter less than 100 μm, joined to a
piezoelectric flexure structure. The assembly requirements are for
positional accuracy of ±0.5 μm, angle between the shaft and flexure of
90°± 0.29° and that the components be undamaged by the process. A
combined Focused Ion Beam and Scanning Electron Microscope machine
(FIB/SEM) with integrated nanoresolution manipulators was used. The
investigation has evaluated potential assembly and joining solutions,
identified modifications to existing equipment and product design and
produced a set of prototypes.
