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 high-voltage electrical connector is described. The connector includes a U-shaped retainer and a spring that extends from a wall of the U-shaped retainer and applies a normal force to couple a terminal to a mating terminal in the high voltage electrical connector. The connector further includes a contact insert configured to be arranged between the terminal and the mating terminal. The contact insert includes an array of resilient protrusions that operate in conjunction with at least one projection that extends from the terminal to establish a plurality of connection points between the terminal and the mating terminal.

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: A window, door, or facade element includes an outer frame composed of out frame bars and a leaf frame composed of leaf frame bars. One or more of the outer frame bars and/or of the leaf frame bars has/have at least the following features: a base profile, on which two fastening grooves that are open in the same direction are formed for fixing a corresponding fastener of a fitting arrangement, which bridges the intermediate space between the fastening grooves. The two fastening grooves have at least one latch for at least one counterpart latch, which can be attached without tools, of a fitting part arrangement. The fitting arrangement has a functional fitting on a fitting plate and at least one support element for supporting the fitting. The support element is designed for direct or indirect latching in the fastening grooves by means of the counterpart latch.

Abstract: A main-frame bar and/or to a wing-frame bar for a main frame and/or a wing frame of a window, of a door, or of a façade element includes a main profiled element having a substantially U-shaped cross-section in single- or multi-piece design, which has, as viewed in a cross-section, a short leg, a long leg, and a transverse leg formed therebetween. A free intermediate space is formed between the ends of the short leg and of the long leg facing away from the transverse leg, a cover element and/or a fitting part extending over the intermediate space at least in some sections. The short leg and the long leg of the main profiled element have multi-function contours on the inner sides thereof facing each other, which multi-function contours completely or partially bound at least the following groove: in each case, a fastening groove open in the same direction on the side facing away from the transverse leg for fastening a corresponding fastening means of the fitting part or of the cover element.

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.
