Abstract: The present invention relates to an apparatus and to a method for compensation of errors of a numerically controlled machine tool, which has at least one controllable machine axis for relative positioning of at least one workpiece relative to one or more machining devices. The method comprises detecting actual measured values of at least one input variable describing a state of the machine tool by means of sensors on the machine tool, providing at least one compensation parameter to be utilized by a control device of the machine tool on the control device of the machine tool and compensating errors on the machine tool on the basis of the compensation parameter provided to the control device. The compensation comprises the compensation of thermal errors, the compensation of geometric errors and the compensation of errors on the basis of the dynamics of the machine.

Abstract: The present invention relates to a control device 200 for use on a numerically controlled machine tool 100, comprising a machine control unit 230 for controlling actuators of the machine tool for a machining process for a workpiece to be performed on the machine tool 100, in particular on the basis of control data, and a monitoring unit 250 for monitoring an operating state of the machine tool 100. In accordance with the invention, the monitoring unit 250 has a computer-implemented neural network 253 (NN), which in particular is designed to read input data from the machine control unit 230 and to output output data specifying an operating state of the machine tool 100.

Abstract: The present invention relates to methods and devices for compensating for a thermally induced change in position on a numerically controlled machine tool, wherein: a characteristic map describing the thermoelastic behaviour of the machine tool is provided to a control system of the machine tool; one or more temperature values are determined by means of one or more temperature sensors on the machine tool; one or more compensation parameters are determined on the control system of the machine tool on the basis of the one or more temperature values determined and of the characteristic map provided; and wherein a temperature-dependent change in position on the machine tool is performed according to the one or more compensation values determined. According to the invention, the characteristic map provided is adjusted or updated by means of a neural network running on a computer.

Abstract: A machine tool comprising a machine frame having dimensionally rigid side walls, each including top-side horizontal guide rails. A compound slide is displaceable in or on the guide rails. On the front of the compound slide is a machining unit comprising a spindle head which is vertically displaceable. A workpiece mounting unit is disposed in the space between the side walls. The workpiece mounting unit may have a workpiece table or a workpiece chucking device. In order to form an enlarged access to the work area of the machine tool, one side wall is shorter at the front than the other side wall. Further, the linear guides or guide rails mounted to the side walls of the machine frame may be aligned at an acute angle ? to the vertical center plane of the machine frame.
