1. A control device for use on a numerically controlled machine tool, comprising:
a machine control unit for controlling actuators of said machine tool for a machining process of a workpiece to be performed on said machine tool on the basis of control data in the form of an NC program, and
a monitoring unit comprising a computer-implemented neural network for process monitoring on said machine tool,
wherein said monitoring unit is configured to read input data from said machine control unit and to output output data indicating an operating state of said machine tool, and
said neural network of said monitoring unit is configured to evaluate output data indicating the operating state of said machine tool for process monitoring on the machine tool in order to detect errors in the machining process,
characterized in that
said neural network of said monitoring unit is configured to read input data from said machine control unit during the ongoing process of machining a workpiece and to output output data indicating a current operating state of said machine tool during workpiece machining; and
said monitoring unit is configured to adjust process parameters, by the neural network, of the machining process present on the machine control unit, which relate to workpiece machining by a work spindle of the machine tool carrying a tool or a workpiece, based on an evaluation of the output data indicating the current operating state of said machine tool.
