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： The present invention is configured such that: when an operator moves a spindle and a table relative to each other using a jog-feed means and when a measurement probe comes into contact with a workpiece fixed on the table, the coordinates of each feed axis are stored; the type of measurement performed by the operator is identified on the basis of the information concerning the feed axis used for moving said measurement probe, the moving direction of the feed axis, the number of times the measurement probe has come into contact with the workpiece, and the number of the jog-feed operation being currently performed by the operator; and the workpiece is measured on the basis of the stored coordinates of the respective feed axes.

摘要： A system for providing state information for at least a part of a tool positioning machine embodied as manipulating machine or as coordinate measuring machine is provided. The system comprises the tool positioning machine defining a machine coordinate system and having a base and a machine structure. The structure comprises a tool head and structural components for linking the tool head to the base, at least one drive mechanism for providing movability of the machine structure relative to the base, a position determining system for deriving at least one coordinate of the machine structure in the machine coordinate system and a controlling unit adapted for controlling movement of the machine structure. The system comprises a calibration setup. A calibration component is mounted on the machine structure and defines a moveable reference point, another calibration component is arranged with defined spatial relation to the base and provides a nominal calibration position.

摘要： A touch probe for a coordinate measuring machine with a processor which is programmed to generate a trigger signal signalling a contact between a stylus of the probe and a workpiece, whenever one of a plurality displacement signals exceeds a corresponding threshold. In addition, or in alternative, a delayed trigger is generated based on a processing a plurality of samples of displacement signals that are stored in a buffer. The processor is programmed to minimize anisotropy of the probe response. Furthermore, the thresholds can be modified during operations based on commands received from the CMM controller.

摘要： The present invention relates to a measuring unit (10) for in-process measurement during a machining operation on machine tool, in particular a grinding machine comprising at least a wheel head arranged at a headstock, comprising a measuring head (14), which is movable between a rest position and a measuring position, and means for moving the measuring head between the rest position and the measuring position. The measuring unit (10) is configured such that the rest position and the measuring position of the measuring head (14) are infinitely adjustable by a user by controlling the movement of the measuring head (14) between the rest position and the measuring position.

摘要： A fabrication and monitoring device for micro probe ball tips includes a magnetic field generator, a 3-dimensional displacement adjusting mechanism, a wire supplier and an image monitoring system. The magnetic field generator includes a U-shaped electromagnet. The 3-dimensional displacement adjusting mechanism includes a 2-dimensional moving platform, a 1-dimensional moving platform, a guiding tube, and a sparking plug. The wire supplier includes a transmission wheel, a pressing roller, a wire feeding roller and a tungsten wire material supplier. The image monitoring system includes a micro objective, a third-generation infinite beam structure lens and a supporting frame. The present invention overcomes an eccentric problem of a tungsten ball and a tungsten rod, and also overcomes a sphericity problem caused by gravity, so as to improve sphericity, eccentric accuracy and enable monitoring of dynamic manufacturing process of the probe ball tips.

摘要： To provide an operation method of a position measuring device capable of accurately and quickly designating a detection point of an object by intuitive operability, such as directly moving the probe with a hand. One aspect of the present invention is an operation method of a position measuring device that includes a measurement head having a probe for designating a detection point of a position of an object, and a moving mechanism for moving the measurement head, and acquires a coordinate of the detection point designated by the probe. The operation method of a position measuring device includes the steps of: using a terminal device including an image acquisition part and a display part to acquire an image of the probe by the image acquisition part and display the image on the display part; detecting a relative positional relation between the probe and the terminal device when having received a movement instruction by the terminal device in a state where an image of the probe is displayed on the display part; and performing a movement control of the measurement head following the movement instruction received by the terminal device by actuating the moving mechanism on the basis of the positional relation.
