Abstract: A device for lubricating contra-sliding parts of a tool device having a drive for effecting the sliding operation, wherein the device has a lubricant dispensing device for the moving parts, which lubricant dispensing device can be actuated by means of the same drive. A method for lubricating contra-sliding parts of a tool device having a drive for effecting the sliding operation, wherein a lubricating pulse is triggered by the following method steps: measuring of the path covered in the operating phase of the sliding parts, recording of the individual path lengths by means of a counter, comparison of the total actual path length with a total path length after which a lubricating pulse is intended to be triggered, and triggering of a lubricating pulse by the same drive for the sliding parts after the cumulative total path length has been reached.

Abstract: A method is provided for assisting an operator in setting optimized machine parameters of a machine tool. The machine parameters are used for controlling the machining. The method comprises manual selecting priority values for at least two mutually dependent target values representing the machining performance and automatically determining the machine parameters based on the selected priority values. A corresponding operator support system is also provided.
