摘要： A batch production system comprising a machine tool for consecutively machining a batch of workpieces into machined pieces, the machine tool comprising a workpiece support configured for supporting the workpieces, a cutting tool, a movement system configured for providing a relative movement between the cutting tool and the workpiece support with at least two degrees of freedom, a control unit configured for controlling the movement system based on numerical control data and compensation data for compensating volumetric positioning errors of the movement system. The numerical control data are based on nominal geometry data representing a target piece that is desired to be achieved when machining the batch of workpieces into the machined pieces.

摘要： Methods for the dimensional inspection of a turbomachine component to be inspected are provided. The turbomachine component includes a first surface delimited by a second peripheral surface substantially transverse to the first surface and a profile defined by a numerical theoretical model with a theoretical surface corresponding to the first surface, the first surface having larger dimensions than the second peripheral surface. The method includes determining theoretical points on the theoretical surface of the numerical theoretical model; calibrating calibration points on the first surface of the component to be inspected; calculating an offset axis for each theoretical point with respect to a corresponding calibration point; and acquiring control points on the second peripheral surface of the component to be inspected from the offset axis.

摘要： A calibrated three-dimensional optical measuring apparatus for the three-dimensional measurement of geometric parameters of a rope has a frame defining and arranged around a rope receiving cavity. A plurality of image acquisition devices is configured to acquire a plurality of digital images of at least one region of an outer surface of the rope. The image acquisition devices are fixed to the frame and arranged around the rope when the calibrated three-dimensional optical measuring apparatus receives the rope in the rope receiving cavity. An attachment device is configured to constrain the calibrated three-dimensional optical measuring apparatus to the rope in a relatively translatable manner with respect to the rope. An electronic digital image processing device is configured to process a multiplicity of digital images and obtain a three-dimensional photogrammetric reconstruction of points of the digital images of the rope acquired by the image acquisition devices.

摘要： A position calibration system and method are disclosed, in which a control unit is provided to control a positioner sensing module to scan a circular positioner provided on a positioning substrate in a first direction and a second direction so as to acquire midpoints of two scanned line segments and acquire an intersection of lines extending from the two center points in a direction perpendicular to the first and the second directions as a calibration reference point, which correspond to a centroid (a center) of the circular positioner. The calibration reference point functions as a reference point for positioning the positioning substrate with respect to the positioner sensing module and is stored in a memory unit. The calibration reference point can be used as a positioning point during installation of a machine and can also be used for calibration of a position of the machine.

摘要： A main reference point PM is provided to a base portion of a shape measuring apparatus including a rotary table. An origin-point relative-value registration includes measuring a main reference point with a probe to acquire a coordinate value of the main reference point and registering as a calibration-reference-point coordinate value Pp, registering a rotation center point of the rotary table as a calibration-rotation-center coordinate value Rp, and calculating a relative coordinate value of the calibration-rotation-center coordinate value Rp with respect to the calibration-reference-point coordinate value Pp and registering as a rotary-table origin-point relative coordinate value ΔD1. A rotary-table origin-point re-registration step includes the steps of measuring the main reference point with the probe to acquire a coordinate value the main reference point and registering as a current-reference-point coordinate value Pc, and adding the rotary-table origin-point relative coordinate value ΔD1 to the current-reference-point coordinate value Pc to calculate a rotary-table origin-point current coordinate value Rc.

摘要： The illustrated embodiments include an apparatus having a programmable, implantable pacemaker with a controllable pacing rate; and a blood pressure monitoring device having an output communicated to the pacemaker. The pacemaker selectively and automatically modulates pacing rate in response to monitored blood pressure to reduce hypertensive blood pressure in a patient or treatment for DCHF (HPpEF). The embodiments also include a. method tor operating a pacing device to treat drug resistant hypertension which includes the steps of monitoring blood pressure; and controlling rate modulation in the pacing device in response to the monitored blood pressure to selectively prevent excessive pacing to reduce mean arterial blood pressure fay either inhibiting rate modulation in the pacing device or by changing rate modulation parameters.

摘要： A method for depositing a piece of band-like elastomeric element on a forming support in a process for building a tyre for vehicle wheels. The method includes feeding a piece of band-like elastomeric element having a predetermined nominal length towards the forming support along a predetermined feeding direction and measuring the actual length of the piece along the feeding direction. If the actual length is lower than or equal to a circumferential length of a deposition surface defined on the forming support, the piece is deposited on the deposition surface while the forming support rotates about a rotation axis thereof. During such deposition the piece is pressed on the deposition surface with a pressing force selected as a function of the actual length.

摘要： A spatial accuracy correction apparatus performs a spatial accuracy correction of a positioner displacing a displacer to a predetermined set of spatial coordinates using a measurable length value measured by an interferometer and a measurable value of the set of spatial coordinates of the displacement body that is measured by the positioner. The measured length value and the measured value for each measurement point are acquired by displacing the displacement body to a plurality of measurement points in order, one or more repeated measurements are conducted for at least one of the plurality of measurement points being measured after conducting measurement of the measured length value and the measured value for each of the plurality of measurement points, and the plurality of points are measured again when a repeat error of the measured length value is equal to or greater than a threshold value.
