A grinding liquid trough arrangement for a grinding machine having a grindstone, wherein said grinding liquid trough arrangement comprises: a trough for grinding liquid formed by a trough wall, wherein the trough is configured to be arranged at a grinding machine having a grindstone such that the trough encloses a portion of a grindstone, wherein, the trough wall comprises at least one metal element which is attractable to magnets, and that, the grinding liquid trough arrangement comprises at least one magnetic element which is configured to be detachable attached to an external side of the trough wall by means of magnetic attraction between the magnetic element and the metal element.

The present invention relates to a transport device (100) for transporting one or more handling devices, each for handling a pallet (300) and/or a workpiece (1) on a machine tool (1000) which is set up on a base surface for machining the workpiece (1), wherein the transport device (100) is freely movable on the base surface for positioning the one or more handling devices relative to the machine tool (1000), in particular within a region in front and/or next to the machine tool (1000) and/or in front and/or next to a working space of the machine tool (1000).

Examples described herein provide for controlling the trajectory of metal chips during a metal cutting operation. Aspects include determining a predicted metal chip formation pattern during the metal cutting operation of a workpiece. Prior to the initiation of the metal cutting operation, the system sets the orientation of the workpiece, and the cutting tool based on the predicted metal chip formation pattern. During the metal cutting operation, the system observes the actual metal chip formation pattern and adjusts the orientation of the workpiece and the cutting tool to control the trajectory of the metal chips, preventing them from contacting the finished portion of the workpiece. Aspects may also involve controlling an electromagnet to create a magnetic field to adjust the trajectory of the metal chips and determining the direction and speed of a cutting fluid applied by the cutting tool based on the predicted and actual metal chip formation patterns.
