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

摘要： An example print apparatus is described as including a fuser roller, a pressure device that generates wear on a section of the fuser roller surface, and a wear detection engine that identifies a degree of wear on the surface of the fuser roller. An example fuser roller may include a tube, a heating element, and a plurality of layers having a detectable pattern. An example print apparatus may include a wear detection engine having an emitter, a detector, and a controller that identifies a wear pattern based on data provided by the detector in response to activation of the emitter and determines a degree of wear based on the identified wear pattern.

摘要： A surface finish stylus and associated methods for a multi-directional scanning probe the stylus having an elongate stylus shaft having a longitudinal axis and one or more contact elements protruding from the elongate shaft for contacting a surface to be measured. The one or more contact elements are configured to enable measurement of surface finish during motion of the stylus shaft relative to a surface along a measurement direction that is non-parallel to the longitudinal axis. The multi-directional scanning probe may be carried by a coordinate measuring machine or machine tool.

摘要： A measuring system (15) includes a measuring arm receiving unit (18) mounted on the housing (49) or on an axial pin (30) connected to the housing (49) for conjoint rotation so as to be rotatable or pivotable about the axis of rotation (D). A measuring arm (16) can be arranged on the measuring arm receiving unit (18). A motor unit (24) generates a motor torque about the axis of rotation (D) on the measuring arm receiving unit (18). The measuring arm unit (18) is mounted by a ball bearing guide unit (39) to be rotatable about the axis of rotation (D) in the peripheral direction and displaceably along the axis of rotation (D) in the axial direction A. An axial position of the measuring arm unit (18) in the axial direction is defined with the aid of a magnetic axial bearing device (46) and is maintained during operation.

摘要： A step gauge and a reference gauge block are placed in a temperature-controlled chamber in parallel with each other. A temperature of the step gauge is changed to a first temperature and a second temperature using a measurement-target temperature adjuster and the temperature-controlled chamber. A distance between a first surface and a second surface of the step gauge is relatively measured at each of the first and second temperatures with reference to a distance between a first reference surface and a second reference surface of the reference gauge block. A coefficient of thermal expansion of the measurement target is calculated from the length of the measurement target at the first temperature and the length of the measurement target at the second temperature.

摘要： A bidirectional displacement detector according to the present invention includes: a displacement detector which includes a first detection element and a second detection element; a base at which the first detection element is provided; an arm which is coupled to the base so as to be rotatable around an arm rotation axis extending in a horizontal direction, and at which the second detection element is provided; and a probe which is coupled to the base so as to be rotatable around a probe rotation axis perpendicular to the arm rotation axis. The probe has a contact part provided at a position away from the probe rotation axis, and a pair of abutment parts which is disposed along a direction of the arm rotation axis and on both sides with the probe rotation axis interposed therebetween and comes into contact with the arm so as to be able to be separated from the arm. Each of the pair of abutment parts is in contact with the arm from the lower side thereof and is biased upward.
