Abstract: A method for aligning a workpiece in a working space of a machine tool having a numerical control system uses a probe. 3D models of the working space, probe, and workpiece are virtually displayed. The workpiece is positioned in the working space and the virtual workpiece is positioned in the virtual working space so that there is an initial coincidence between positions thereof. The probe is manually positioned relative to the workpiece, wherein a planned probing point and probing direction are selected based on a minimum distance of the virtual probe from the virtual workpiece, and are displayed. Enabling of the probing is based on quality of the planned probing point, and, when enabled, a probing operation is triggered, and coordinates of a probing point are determined. The position of the workpiece is recalculated using these coordinates, and the position of the virtual workpiece is updated.

Abstract: An acceleration sensor, particularly a Coriolis rotation-rate sensor, having a swinging structure that is movably suspended on a substrate (base) and can be deflected due to an acceleration effect, the sensor further having an arrangement for generating a planar swinging movement of the swinging structure, particularly a rotational swinging movement, and an evaluating arrangement for detecting a deflection of the swinging structure that is stipulated by acceleration, particularly for detecting a Coriolis acceleration. The swinging structure (12) is rotatably suspended so as to perform a planar swinging movement, and should perform a planar, rotational swinging movement.
