摘要： A measurement probe (12, 110, 250), such as a touch trigger or analogue probe, is described that comprises a deflectable stylus portion (14) and a wireless communications unit (18) for transmitting stylus deflection data to a remote probe interface (20, 104, 254). The wireless communications unit (18) is arranged to transmit digital data packets comprising stylus deflection data and a probe identity code. The wireless communications unit (18) allows said probe identity code to be set by a user. The measurement probe (12, 110, 250) may communicate with an associated probe interface (20, 104, 254) over a radio frequency (RF) spread spectrum link (106).

摘要： A method of determining the eccentricity of an encoder scale member (10) of a rotary encoder is described. The method comprises taking an encoder scale blank having a geometric centre (N) and mounting the encoder scale blank centred about a second centre (P). A scale can then be produced on the encoder scale blank thereby forming an encoder scale member (10), the scale of the encoder scale member being centred about the second centre (P). Any eccentricity between the geometric centre (N) and the second centre (P) 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 (e.g. to shaft 30) wherein it rotated about a third axis (Q). 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.

摘要： A tool measurement apparatus for a machine tool includes a transmitter portion (100) including a light source (102) for generating a light beam (104) and a receiver portion (300) including a detector for detecting the light beam (104), the light beam being passed from the light source to the detector along an optical path. At least one of the receiver portion (300) and the transmitter portion (100) comprises a protection device including a gas expulsion aperture (108) configured to expel a bleed gas supplied from an external gas source. The optical path also passes through the gas expulsion aperture (108). The protection device further comprises a check valve (112; 200) located in the optical path. The bleed gas is supplied to the gas expulsion aperture (108) through the check valve (112; 200) and the flow of the bleed gas through the check valve (112; 200) causes the check valve to adopt an open configuration defining a passageway through which the light beam (104) can pass.

摘要： A method and apparatus are described for determining the runout of a tool (12) retained by a rotatable spindle of a machine tool using a tool edge sensor, such as a non-contact tool setter (2), mounted to the machine tool. The spindle is arranged to rotate the tool, which may be a fluted cutting tool, about a spindle centre line (20). The technique comprises rotating the spindle into three or more rotational orientations and using the tool edge sensor to measure a position of the edge of the tool (12) for each of the three or more rotational orientations. A tool centre point is found by fitting the positions of the tool edge to a function and a difference in position between the tool centre point and the spindle centre line (20) is used to determine a runout of the tool.

摘要： An optical tool measurement device (2) for a machine tool is described. The device comprises a light source (10) for directing light towards a tool-sensing region (13) and a sensor (14) for detecting light from the tool-sensing region (13). A shutter assembly (40) for selectively protecting the sensor (14) from contamination is also provided. The shutter assembly (40) is configured to provide a closed configuration in which the sensor (14) is covered by the shutter assembly (40) thereby preventing contamination of the sensor (14) and an open configuration in which light can pass to the sensor (14) through a first aperture (72;102) of the shutter assembly (40). Furthermore, the shutter assembly (40) is additionally configured to additionally provide a constricted configuration in which light can pass to the sensor through a second aperture (74;104) of the shutter assembly (40), the second aperture being smaller than the first aperture. In this manner, the device (2) has enhanced resistance to contaminants, such as swarf and coolant, present in the machine tool environment.

摘要： A surface finish stylus(50)is described that includes an elongate stylus shaft (52;100) and a contact element (56;102) protruding from the elongate shaft for contacting a surface to be measured. The contact element (56;102) is deformable and the stylus shaft comprises a clamp for retaining the contact element(56;102), the contact element (56;102) being deformed by the clamp. The contact element (56;102) may comprise a metal, such as chromium steel or nitinol. The contact element (56;102) comprises one or more regions of weakness (82) to cause a required deformation when retained by the clamp. The surface finish stylus (50) may be used with a surface finish measurement probe (20) or the like.

摘要： A method and an apparatus are described for assessing the profile of a tool (50; 80; 170) using a non-contact tool setting apparatus (150) that comprises a transmitter (10) for emitting a light beam (12; 152) and a receiver (14) for receiving the light beam. The receiver (14) generates a beam intensity signal describing the intensity of received light. The non-contact tool setting apparatus (150) is mounted to a coordinate positioning apparatus, such as a machine tool, that allows the tool (50; 80; 170) to be moved relative to the non-contact tool setting apparatus (150). The method comprises using the coordinate positioning apparatus to move the tool (50; 80; 170) relative to the non-contact tool setting apparatus (150) along a tool inspection path (56;88), the tool inspection path being selected so that the light beam is traced substantially along a periphery of the tool (50; 80; 170) to be inspected. Beam intensity data is collected describing the beam intensity signal that is generated by the receiver (14) as the tool inspection path (56;88) is traversed and analysis of the collected beam intensity data is used to assess the tool profile.

摘要： A method of operating coordinate positioning apparatus having a measurement probe (18) is described. The method comprising a step of taking a first part (24) in a series of nominally identical parts, at least a first reference geometrical property associated with one or more features of the first part (24) being known. A step is also performed of using the coordinate positioning apparatus to measure the one or more features of the first part (24) and determining therefrom a first measured geometrical property that corresponds to the first reference geometrical property. A first property correction value is then determined that describes a difference between the first reference geometrical property and the first measured geometrical property. The coordinate positioning apparatus is then used to measure the one or more features of one or more further parts in the series of nominally identical parts and, for each further part, a further measured geometrical property is determined that corresponds to the first reference geometrical property. The first property correction value is then applied to each further measured geometrical property. A corresponding coordinate positioning apparatus is also described.
