摘要： A metrology instrument, such as a probe, probe head, stylus or stylus arm, for mounting on a coordinate position apparatus. The metrology instrument is at least partially constructed from at least one sheet of thermally stable metallic material with a low cooefficient of thermal expansion, which is folded to form a three dimensional structure. The at least one sheet of thermally stable material is utilised in the metrology loop of the metrology instrument. In this way a lightweight and thermally stable metrology instrument can be constructed.

摘要： A coordinate positioning apparatus comprising a load bearing structure. The load bearing structure comprises at least one elongate corner piece providing at least two bearing surfaces, one on each side of the corner, for a carriage moveable along the load bearing structure, and at least one piece of sheet material which extends along the at least one elongate corner piece and provides at least one load bearing facet.

摘要： A rotary gas bearing (20) is described that comprises a first part (24) rotatable relative to a second part (22). The first part (24) comprises a support member (26) and a first portion (30) and a second portion (32) attached to the support member (26). The first portion (30) comprises a first bearing surface (34) and the second portion (32) comprising a second bearing surface (36). Both the first portion (30) and the second portion (32) are attached to the support member (26) by screw thread connections. The second part (22) may comprise complimentary bearing surfaces (38,40). Epoxy may be used to fix the first and/or second portions (30,32) to the support member (26). A method of determining the bearing working gap by measuring gas flow through the bearing is also described.

摘要： A bearing arrangement for an articulatable support (6) comprises bearing assemblies (20/28, 22/29, 24/30 and 26/32). In one embodiment the assemblies comprise a ball (20, 22, 24, 26) and aperture (40 figure 2) having sliding contact at discrete areas (36) during relative rotation. In another embodiment the sliding contact may be formed at a ball (20, 22, 24, 26) and a plastics e.g. P.T.F.E. support (84, 85 figures 10 and 11). Resilient displacement of the bearing contact along a rotational axis (A and B) is provided by planar spring supports (28, 32) and rigid support is provided by supports (29 and 30).
