The invention relates to a support device ( 200 ) for supporting a rod-shaped workpiece ( 110 ) for a machine tool ( 100 ) along a longitudinal axis (L) of a support area ( 220 ). The support device ( 200 ) comprises at least one twin support ( 210 ) adapted to support a section of the workpiece ( 110 ) in the support area ( 220 ), wherein the twin support ( 210 ) comprises two support elements ( 300, 310 ) each being rotatable around a rotational axis (R 1 , R 2 ), wherein each of the rotational axes (R 1 , R 2 ) is perpendicular to the longitudinal axis (L), wherein each support element ( 300, 310 ) comprises a quadrant shaped support surface ( 330 ) forming together a semicircular shaped support surface ( 340 ) adapted for supporting a section of the workpiece ( 110 ), wherein the support area ( 220 ) comprises an open side opposed to the semicircular shaped support surface ( 340 ), and wherein the support elements ( 300, 310 ) are adapted to provide a varying diameter of the semicircular shaped support surface ( 340 ) based upon the position of rotation around the rotational axis (R 1, R 2 ) in order to support varying workpieces ( 110 ).

The present disclosure relates to a component for a machine tool, having a component main body and having at least two layers arranged thereon for identifying wear, wherein the layers for identifying wear are applied to a wear region of a component of the machine tool and wherein at least one of the two layers is a signaling layer for indicating the wear.

The invention relates to a method for controlling a jet cutting device ( 15 ) having a cutting tool ( 21 ), by means of which at least one workpiece part ( 18 ) can be cut out of a workpiece ( 16 ) along a cutting contour ( 17 ). At least one cutting plan ( 48 ) for the workpiece ( 16 ) having at least one cutting contour ( 17 ) for at least one workpiece part ( 18 ) to be cut out of the workpiece ( 16 ) is specified (step a)). Subsequently, the relative position of the workpiece ( 16 ) and/or of the cutting plan ( 48 ) and/or of the workpiece part ( 18 ) to be cut out is determined (step b)). Then, the relative position of the at least one support point ( 32 ) of the workpiece support ( 30; 130 ) is determined (step c)). Subsequently, at least one risk region ( 28 ) on the cutting contour ( 17 ) of the workpiece part ( 18 ) to be cut out is determined (step d)), followed by the defining of at least one starting-cut point ( 29 ) and/or one cut-away point ( 129 ) for the cutting tool ( 21 ) on the cutting contour ( 17 ) of the workpiece part ( 18 ) to be cut out. The invention further relates to a computer-implemented method and to a jet cutting device ( 15 ).

A device and a method for monitoring beam treatment of a workpiece are provided. The device includes at least one illuminating device ( 12 ) for illuminating a treatment region of the workpiece during first time intervals; a detecting device ( 15 ) for detecting an electromagnetic radiation emanating from the treatment region; and a processing device ( 19 ) for separate processing of the electromagnetic radiation detected within the first and within second time intervals. Moreover, a device and a method for laser beam treatment of a workpiece are provided.

This disclosure relates to a workpiece support for a machine tool having at least two parallel carriers which are spaced apart from one another, define a cutting grate space and multiple cutting grate elements arranged in the cutting grate space at right angles to the carriers. Each carrier has a support area for the cutting grate elements extending towards the cutting grate space. At least two cutting grate elements, each having two support surfaces facing the carriers for resting on the support areas of the two carriers. The undersides of the at least two cutting grate elements remaining next to the support surfaces in the area of the support areas and are set back from the support surfaces so that the at least two cutting grate elements rest only with the support surfaces. The at least two cutting grate elements each have two fixing elements.
