Abstract: A coordinate measuring machine and a method for operating a coordinate measuring machine, and a rotary table module for a coordinate measuring machine with a rotary table for receiving a workpiece and a rotary table block are provided. The rotary table is supported on a rotary table side rotatably about a rotary table axis. The rotary table block has, opposite the rotary table side of the rotary table block, a bottom side with which the rotary table module can be supported on a measurement table of the coordinate measuring machine. The rotary table block has a further supporting side with which the rotary table block is supportable on the measurement table of the coordinate measuring machine and which differs from the bottom side in its alignment.

Abstract: A device has a displaceable device part, a drive, which is configured to drive the displaceable device part and to thus induce a movement in the displaceable device part, and a control unit, which is connected to the drive and is configured to control the drive. The device further has a first signal transmitter for determining a position and/or speed of the displaceable device part. The first signal transmitter and/or a first signal evaluation device, which is connected to the signal transmitter, are connected to the control unit such that the control unit receives information from the signal transmitter about the position and/or speed of the displaceable device part during operation of the device and controls the drive on the basis of the information received. A second signal transmitter of the device serves to monitor and/or redundantly determine the position and/or speed of the displaceable device part.

Abstract: A concrete form block for construction of a building includes first and second panel devices, each having inner and outer faces separated by ribs. Projecting connectors are disposed on the inner faces and each has a pin-receiving aperture. U-shaped couplers are used to connect the two panel devices together so that their inner faces are parallel. Each connector has first and second connecting pins and these are received in the apertures of the connectors of the panel devices, with each pin being pivotable in its aperture after insertion. The panel devices can be moved from a collapsed configuration having at least a reduced space between the inner faces and an in-use configuration with more space between these faces. There is also disclosed a panel structure having upper and lower channel forming frames connected to an outer wall portion thereof. These form a channel for receiving equipment for utilities.

Abstract: In a method for reliably monitoring the speed of a moveable coordinate measuring device, a first value of the speed is calculated from measured values of the coordinate measurement system. The measured values contain information on positions of the coordinate measuring device. The measured values are further used to determine the coordinates of a measurement object. A second value of the speed is ascertained from measurement signals of at least one additional movement sensor. The measurement signals can also be used for controlling a drive device of the coordinate measuring device. A fault signal can be generated if the first value and/or the second value deviate from one another, from a predetermined value and/or a limit value according to a predefined criterion.

Abstract: In a method for operating a coordinate measuring machine and to a coordinate measuring machine, a coordinate measuring device, of the coordinate measuring machine is moved in at least one direction while being driven by an electric motor. An electrical drive current which flows through the electric motor for moving the electric motor and, move the coordinate measuring device is measured. A limit value for the electrical drive current is determined on the basis of a desired speed and/or on the basis of a desired acceleration with which the electric motor or the coordinate measuring device is intended to move. If the electrical drive current reaches the limit value determined and/or if the electrical drive current exceeds the limit value determined, the coordinate measuring device is changed to a predefined state, by virtue of the computer or the microcontroller switching off one of the switches disposed in the current path.
