摘要： A sensor adjustment mechanism for a coordinate measuring machine, comprising a sensor supported by at least one joint so as to be rotatable or pivotable about at least one axis, a change interface for releasable coupling of the sensor adjustment mechanism to a measuring head of the coordinate measuring machine, and a fixing device blocking the at least one joint. The change interface comprises a first component and a ferromagnetic second component, which is supported in such a way as to be movable relative to the first component. The sensor adjustment mechanism can be fixed on the measuring head by means of a magnetic fixing force exerted on the second component. The magnetic fixing force exerted on the second component causes a movement of the second component relative to the first component. The fixing device is actuated by the movement.

摘要： A method and equipment for dimensional measurement of a micro part based on fiber laser with multi-core fiber Bragg grating probe are provided, wherein a multi-core FBG probe with FBGs (12,29) inscribed in the core or cores out of the center of the multi-core fiber is used to transform the two-dimensional or three-dimensional contact displacement into the spectrum shifts with a high sensitivity. At the meantime, the FBGs in the multi-core FBG probe (12,29) work as the wavelength selection device of the fiber laser, the wavelength of the fiber laser will change thereby. So the contact displacement is finally converted into the wavelength change of the fiber laser. The method and equipment have the advantage of high sensitivity, low probing force, compact structure, high inspecting aspect ratio and immunity to environment interference.

摘要： A system and method are provided for operating a touch probe for a coordinate measuring machine, wherein a value is permanently stored in the touch probe corresponding to an accumulated number of trigger signals generated in the touch probe over its operating history. For a non-erase cycle during which an erasable trigger counter block (e.g., included in a flash memory) of the touch probe is not erased, increasing values of an accumulated trigger count are stored in N address locations of the erasable trigger counter block. After all of the N address locations have been used, an erase operation sequence is performed, and a new non-erase cycle is initiated for repeating the process. In various implementations, the touch probe may not include an embedded processor or battery, for which the types of circuitry and methods that may be utilized for maintaining and storing the accumulated trigger count are correspondingly limited.

摘要： A fixture enables a stylus extension to be angularly aligned relative to an adapter plate that mounts onto a CMM probe head. Alignment may be carried out on a flat surface remotely from the CMM. The adapter plate is mounted to the fixture, which includes an access hole providing access to adjustment screws at the rear of the adapter plate. One or more lateral extensions are connected to the stylus extension to define a calibration axis perpendicular to a probe axis of the stylus extension and perpendicular to a central axis of the adapter plate about which angular alignment is desired. Angular adjustments of the stylus extension are made while the adapter plate is mounted to the fixture, and a degree to which the calibration axis is parallel to a plane of the flat surface is detected, for example using a dial indicator engaging points on the lateral extension(s).

摘要： A probe (100) comprises a frame (2), a movable armset (3) and a processing circuit (30; 30′) for processing signals. The processing circuit is able to individually detect the state of contacts (13) defined by the cooperation between mechanical elements of the armset and mechanical elements of the frame, that is the closing or opening of the contacts, and provide a signal indicative of a rest position of the probe when it detects no more than one open contact. A method for processing signals uses said circuit in order to provide a signal indicative of a rest position of the probe. The circuit and the method for processing signals are advantageously implemented for processing the output signals of a touch probe adapted to check dimensions or position of a workpiece in coordinate measuring machines and machine tools.

摘要： A touch probe circuit comprises a displacement sensor having a sensor signal responsive to touch probe stylus displacement, an offset compensation controller, and a difference amplifier. The offset compensation controller provides a varying offset compensation signal to compensate drift in a rest-state signal component of the sensor signal. The difference amplifier inputs the offset compensation signal and the sensor signal and amplifies the difference therebetween to provide an offset compensated displacement signal, which is output to a touch trigger signal generating circuit that provides a touch signal when the stylus touches a workpiece, and is also output to the offset compensation controller. The offset compensation controller portion provides a feedback loop that inputs the offset compensated displacement signal and outputs a responsive low pass filtered offset compensation signal to the difference amplifier, in order to provide the offset compensated displacement signal.

摘要： A method and a device can measure machine error of an axis of rotation in a tool post having a touch probe without restriction of an angular range of an angle of rotation. Directions of a measurement plane and a measurement axis in a five-axis measurement are switched in correspondence to a range of the angle of rotation in a touch probe. The five-axis measurement is carried out by setting a position in a direction of a measurement axis in a measurement plane to a position where a reference sphere does not interfere with a lever rod of the touch probe as occasion demands. The five-axis measurement is carried out, for example, by setting the measurement plane to a position which is perpendicular to a line connecting an estimated center of the reference sphere and a center of a tip sphere or the lever rod of the touch probe.

摘要： A multi-dimensional measuring system is disclosed wherein a laser-based tracking unit communicates with an optical target on a measurement instrument to obtain position and orientation information about the instrument. The optical target incorporates a plurality of encoders configured to provide a full 360° working range in pitch, yaw and roll. Full working range in pitch and yaw is achieved through the use of a pitch/yaw angular encoder. Full 360° working range in roll is achieved with a combination of a level sensor and a 360° angular encoder, which are fixed to a pendulum so that the level sensor is always aligned to gravity. Use of a slip-ring mechanism ensures the unlimited full working range in roll. The measurement instrument includes a scanner integrated with a probe receptacle adapted to accept a probe assembly to provide the instrument with both a scanning measurement and a probe measurement capabilities. Incorporation of an additional probe receptacle provides increased measurement capability and flexibility. The optical target with its full 360° angular working range in pitch, yaw and roll can be utilized independently of the measurement instrument. In combination with a laser tracker, the optical target can be attached to any object or surface to be measured, or alternatively, it can be attached to a movable device and the position of that device monitored.
