摘要： A rotary ring for use in scale reading apparatus, comprises a flexible ring (10) which has scale markings (14) provided on a surface thereof. The rotary ring is mounted onto a machine part (22) by providing the machine part with a region of increased diameter (26) and stretching or shrinking the flexible rotary scale (10) over said region of increased diameter. The manufacturing tolerance of the rotary scale or differential e.g. thermal expansion is thus taken up by stretching or shrinking it into place. The region of increased diameter may comprise an annular protrusion or an O-ring, for example.

摘要： A method of making metrological scale for scale reading apparatus includes directing a laser beam onto a scale substrate (12). The laser parameters are such that the local area of the scale substrate (12) on which the laser beam is incident is caused to be displaced, thus creating scale markings (16, 20, 22).

摘要： A method of determining the eccentricity of an encoder scale member of a rotary encoder includes taking an encoder scale blank having a geometric center and mounting the encoder scale blank centered about a second center. A scale can then be produced on the encoder scale blank thereby forming an encoder scale member. The scale of the encoder scale member is centered about the second center. Any eccentricity between the geometric center and the second center is measured by, for example, measuring any change in the apparent radius of the encoder scale member. The encoder scale member may then be mounted in a working location wherein it is rotated about a third axis. The eccentricity when mounted in the working location may be matched to that measured during manufacture thereof and/or the eccentricity errors arising from both manufacture and mounting of the encoder scale member may be determined.
