Abstract: A measuring system for acquiring measured values by scanning, including an interface for connection to a control unit of a machine. The system is arranged on a movement axis of the machine, and an object can be measured by a measuring instrument of the system. During the measurement of the object, the measuring instrument generates a measured value that is stored in a control unit, that processes and stores the measured value. The control unit has a control module that reads out a position coordinate from the machine via the interface and compares the read-out position coordinate with a specified coordinate target range, and/or compares a time of a timer with a specified point in time, and releases a trigger signal if the control module detects that the position coordinate lies in the coordinate target range and/or if the time has reached or passed the specified point in time.

Abstract: The invention relates to an ultrasonic measuring unit for attaching to a measuring instrument. The measuring instrument is designed in such a way that the measuring instrument can be arranged on a movement axis of a machine. When the ultrasonic measuring unit is arranged on the measuring instrument, an ultrasonic measurement can be carried out by means of the ultrasonic measuring unit. The ultrasonic measuring unit comprises a tubular sleeve and an elastic carrier element. The tubular sleeve surrounds the elastic carrier element. The elastic carrier element consists of a material that conducts ultrasonic waves. At a first end of the tubular sleeve, the elastic carrier element protrudes beyond an outer edge of the tubular sleeve. The tubular sleeve and the elastic carrier element are intended to contact, in particular directly, the surface to be measured, during a probing process of the measuring instrument.

Abstract: A device for calibrating the speed of a movement axis of a machine, including a measuring instrument and a measuring assembly having first and second measuring elements provided at a defined and known distance from one another on the measuring assembly. The measuring assembly is arranged on a workpiece receptacle of the machine, and the measuring instrument performs measurements with a known target frequency. When the device is arranged on the machine and the measuring instrument is moved at a known target speed of a movement axis of the machine from the first measuring element to the second measuring element, the measuring instrument interacts with the respective measuring element to determine an interaction date or a detection date. The device detects starting from the first interaction date or detection date to the second interaction date or detection date, a number of measurements of the measuring instrument.

Abstract: A measuring system for detecting measured values by scanning, including a measuring instrument. The measuring system can be arranged on a movement axis of a machine tool or a measuring machine. An object is measured by the measuring instrument generating a measured value during the measurement of the object. The measuring system includes a control unit to process and store the measured value, and a memory unit to store the detected measured value. The measuring system correlates a first measured value with a first position coordinate of the measuring instrument and, starting from the correlation of the first measured value with the first position coordinate, assigns position coordinates uniquely to further measured values detected by the measuring instrument since a movement speed and a movement direction of the measuring instrument during or at the time of the detection of the measured values are known to the measuring system.

Abstract: A tool holder, in particular for a measuring sensor, with an interface to a spindle of a machine tool is proposed. The tool holder comprises, as seen from the interface for the spindle, a material portion which differs from the customary basic material of a tool holder in a lower coefficient of linear expansion ? and/or in a lower heat conductivity ?. According to the invention, the material portion affords thermal decoupling between the tool-side portion of the tool holder and a tool received therein from the tool spindle for reducing a length change on account of an introduction of heat coming from a comparatively hot tool spindle.

Abstract: A method is proposed for measuring tools on a machine tool with a measuring device, wherein by means of a movement of a spindle of the machine tool the measuring device is temporarily positioned at a measuring point on the machine tool in order to carry out one or more measurements, the measuring point differing from a spindle mount. Furthermore, a measuring apparatus is proposed which is embodied in such a way that the measuring device can be positioned at a measuring point on the machine tool for a measuring operation by means of a spindle movement of a machine tool, said measuring point differing from a spindle mount.
