Embodiment Construction

[0028] figure 1 A machine tool 1 for laser machining is shown, which has a beam-guiding optics with a plurality of optical elements 2.1 to 2.5 for guiding a laser beam 3 to a laser machining head 4 on. In order to move the laser processing head 4 along a processing table defining the working plane 5 in the first spatial direction X of the XYZ coordinate system, the laser processing head 4 is fixed on a carriage that can travel in the first spatial direction X 6, as indicated by the double arrow. The laser processing head 4 can also travel in the working plane 5 in the second spatial direction Y by moving the laser processing head 4 along the carriage 6 , as also indicated by the double arrow. In this way, the laser machining head 4 can be moved in the two spatial directions X, Y over the entire working plane 5 of the machining table and in this case process the workpiece 7 positioned on the machining table. In addition, the laser processing head 4 can also be moved relative...

Abstract

The invention relates to a contact sensor (11) with a sensor body (12) which can be attached to a laser processing head (4) of a machine tool for the processing of preferably plate-like work pieces, particularly metal sheets. The sensor body (12) can be inserted on the laser processing head (4) in place of a laser processing nozzle, and an electrically conducting and electrically contacting measuring probe (15) is guided in the sensor body (12), and the measuring probe is movable in a sliding direction from a resting position in which the measuring probe (15) does not project above the sensorbody (12) to a measuring position in which the measuring probe (15) projects out of the sensor body (12). The invention relates in addition to a machine tool with such a contact sensor (11) and to a method for the detection of the condition of a work piece edge in accordance with such a contact sensor (11).

Description

technical field [0001] The invention relates to a touch sensor with a sensor body, which can be fastened to a laser processing head of a machine tool for machining preferably plate-shaped workpieces, in particular sheet metal, and a touch sensor with such a touch sensor. Machine tool and a method for detecting the position of an edge of a workpiece by means of a touch sensor having a sensor body attached to a laser machining head of a machine tool for machining preferably plate-shaped workpieces, in particular sheet metal . Background technique [0002] In a machine tool for laser machining, the position of the workpiece needs to be detected as precisely as possible before the workpiece can be machined. If the generally plate-shaped workpiece or the sheet is not detected at an oblique position, this can lead to incorrect machining of the workpiece and thus a sharp increase in the number of rejects. In the prior art, the sheet metal position is detected, for example, by opt...
