摘要： A roughness measurement sensor (15), comprising a sliding element and a sensor tip (15.4), wherein the sensor tip (15.4) is arranged in the region of the extremal end of a sensor arm (13.1) which has a longitudinal extension parallel to a longitudinal axis (LA) and is mounted in a lever-like manner. In some embodiments, the sliding element is formed in the manner of a skid (15.3), and the skid (15.3) lies, as viewed in a sectional plane (SE), perpendicularly to the longitudinal axis (LA), laterally adjacent to the sensor tip (15.4).

摘要： A roundness measuring machine includes: a base; a table rotatable relative to the base; a probe configured to scan a surface of a workpiece mounted on the table; a motor configured to rotate the table; and a control device configured to control a rotation of the motor. The control device includes: a starting current detector configured to detect a starting current of the motor; and an acceleration/deceleration time setting unit configured to detect at least one of acceleration time and deceleration time for the motor in accordance with the starting current. The roundness measuring machine can suitably set the acceleration time and the deceleration time for the motor corresponding to the inertia moment of the workpiece mounted on the table.

摘要： A device for measuring the straightness of a rod-like work piece includes a support for the rod-like work piece. The support has multiple sections, each of which has a support surface. At least one force sensor is provided to measure the force applied by the work piece onto the support surface in a direction that extends essentially transverse to gravitational acceleration.

摘要： A surface pressure measuring device includes an abutting plate, a lift, a probe, a piezo actuator and a controller. A pinhole is formed in the abutting plate at an abutting surface that abuts a target. The lift causes the target to abut the abutting surface such that the target is compressed to a predetermined thickness. The probe is inserted through the pinhole to be movable in an axial direction of the pinhole. The piezo actuator holds a state in which a tip surface is flush with the abutting surface as the probe resists a repulsive force received from the target while the lift causes the target to abut the abutting surface. The controller calculates a local surface pressure of the target from a load applied to the probe and an area of the tip surface of the probe.

摘要： A lens-measuring machine includes: a table rotatable around a rotation axis; a lens holder that holds a workpiece in a form of a lens, the lens holder being placed on the table so that an optical axis of the lens becomes orthogonal to the rotation axis; a contact tip that contacts a measurement surface of the lens; an angle sensor for detecting a rotary angle of the table; a displacement detector for detecting a displacement of the contact tip; and a controller for calculating coordinates information of the measurement surface of the lens in a form of polar coordinates, whose origin is at the rotation axis, based on displacement of the contact tip for every predetermined rotary angle of the table, the controller converting the calculated polar coordinates into Cartesian coordinates.

摘要： A device and method for measuring dimensional variation of a part, particularly total runout, is provided. The device includes an indicator check body, a clamping device within the indicator check body and an end cap that engages the indicator check body and the clamping device. When the indicator check body and the clamping device are engaged, the device is secured to the part allowing dimensional variations to be measured along the surface of the indicator check body.

摘要： A robotic coordinate measurement machine (CMM) having a contact direction sensitive (CDS) probe is usable to detect internal dimensions for an object of interest. A robot arm may contact a surface with the CDS probe which may then detect a magnitude and direction of the resulting reaction force. The robotic CMM may monitor the magnitude and/or direction of the reaction force while the CDS probe is being slide across a surface to determine dimensions for the surface. Changes in the reaction force sensed by the CDS probe may be used to identify contact with other surfaces of contours in the surface the CDS probe is being slid across. A path of the CDS probe may be altered based on the contact with other surfaces or the contours.
