Publication number: 20230152074Abstract: A position of a movable part of a coordinate measuring machine (CMM) is determined repeatedly. A position value of the part is measured at a reference location. First and second acceleration values are measured at a first and second measuring location. The second measuring location is closer to a measuring sensor than the first measuring location and the first measuring location is closer to the reference location than the second measuring location. A target and/or actual state value is supplied to a model of the CMM. Estimators are modelled. The model is supplied with a position deviation based on the estimator of the position deviation and deviation based on the estimator of the deviation and the deviation of the measured first and second values. The position of the part is determined from the measured position value in relation to the reference location based on the estimator of the position deviation.Type: ApplicationFiled: November 15, 2022Publication date: May 18, 2023Inventors: Udo Gruber, Guenter Grupp

Patent number: 10852122Abstract: A method and an arrangement for capturing an object by a movable sensor are provided. The method includes moving the sensor relative to the object and repeatedly ascertaining an instantaneous position of the sensor by a position measurement system, outputting the position to an evaluation device at a predetermined time point, repeatedly capturing the object by the sensor during a capturing time interval and outputting a measurement signal corresponding to the information captured during the capturing time interval. For at least one capturing time interval, a point in time of the capturing of the object is determined which lies within the capturing time interval, position values are ascertained and outputted at points in time which include the point in time of the capturing, and a position main value is ascertained based on the position values which approximates the position of the sensor at the point in time of the capturing.Type: GrantFiled: March 26, 2019Date of Patent: December 1, 2020Assignee: Carl Zeiss Industrielle Messtechnik GmbHInventors: Rudolf Kern, Guenter Grupp, Kai Schaeffauer

Patent number: 8115440Abstract: A machine part, such as a laser, is moved along at least one axis of movement relative to a workpiece. Position pulses are generated by means of an incremental encoder, with the number of position pulses in a position pulse train being representative of the movement position of the machine part.
