摘要： Re-orientation of a stylus (30) or measurement probe (12) can be accomplished by engaging a part of the stylus or probe with a fixed part (50) and moving the probe in a spherical path centred at the engagement. The engagement (50) is spaced from the stylus tip (34) and avoids bending of the stylus during re-orientation. The re-orientation can take place into a plurality of e.g. repeatable rest positions by virtue of a kinematic array (e.g. balls (122) and rollers (120) Fig 2).
摘要翻译：触针（30）或测量探针（12）的重新定向可以通过将一部分触针或探针与固定部分（50）接合并以探针作为中心位置的球形轨迹移动来实现。接合（50）与触针尖端（34）间隔开，并避免在重新定向时触针的弯曲。重新定位可以发生到多个例如凭借运动学阵列（例如球（122）和滚筒（120），图2）可重复的休息位置。

摘要： A method and apparatus for controlling or programming a measurement path for a probe mounted on a coordinate positioning apparatus (e.g. an articulating probe head mounted on a CMM) which enables both the position of the probe tip and the orientation of the probe to be varied. In a first mode, the position of the probe tip is adjusted. In a second mode the orientation of the probe is adjusted, whilst keeping the location of the probe tip unchanged. This may be achieved either online on the coordinate positioning apparatus or offline in software.

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： An analogue probe for a machine tool apparatus, comprising a probe body and a stylus member movably secured to the probe body in a suspended rest position via a suspension mechanism. A sensor is provided for measuring the extent of displacement of the stylus member relative to the probe body from a rest position. The analogue probe further comprises a first compliant sealing member extending between the probe body and stylus member such that the sensor is contained within a chamber sealed from external contaminants. The analogue probe also has for a suppressor for suppressing movement of the stylus member away from its suspended rest position induced by changes in the chamber's internal pressure and/or changes in the analogue probe's operating environment.
