摘要： A method of determining the sub-divisional error of an encoder apparatus that is configured to measure the position of relatively moveable parts of an apparatus on which an inspection device for inspecting an artefact is mounted. The method includes causing the inspection device to obtain measurements which includes relatively moving the relatively moveable parts of the apparatus, and using the measurements to determine the encoder apparatus' sub-divisional error.

摘要： A method of fabricating a bearing surface (11,13) for a gas or air bearing (2) is described. The method comprises taking a bulk bearing portion (30;44) having at least one bearing surface region and providing a coating (32;42) on the bearing surface region to define at least one gas pocket (34;40). The at least one gas pocket (34;40) has a depth substantially equal to the thickness of the coating (32;42). In one example, laser ablation is used to remove part of the coating (32;42) to form the gas pockets (34;40). The coating (32;42) may be an anodised coating and the bulk bearing portion (30) may be formed from aluminium. An air bearing component formed using the method is also described.

摘要： A method and apparatus for measuring a surface using a surface sensing device mounted on a scanning head on a member of a coordinate positioning apparatus. The coordinate positioning apparatus may be operated to produce relative movement between the scanning head and the surface profile and the scanning head includes a drive for producing rotational movement of the surface sensing probe about one or more axis. A desired measurement profile on the surface which the surface sensing device will track and the desired motion of the orientation of the surface sensing device as the surface' sensing device follows the measurement profile are defined. This data is used to derive the required path of the relative motion between the member of the coordinate positioning apparatus and the surface, such that the surface sensing device prescribes a trajectory along the measurement profile.
