20140131922 | METHOD AND DEVICE FOR MACHINING A WORKPIECE, MORE PARTICULARLY FOR PRODUCING CUTTING TOOLS - A method for machining a workpiece by means of a laser beam, in which material of the workpiece is removed layer-by-layer according to predetermined definitions to produce a workpiece by traversing the exposed workpiece surface in lengths across the entire surface with a laser beam in order to vaporize and/or combust workpiece material. In a first material removal phase, the laser beam is guided relative to the workpiece over the workpiece surface by adjustable mirrors inside the laser tool, more particularly without mechanical control axes being moved to adjust the relative position between the laser tool and the workpiece. In a second material removal phase, the laser beam is guided relative to the workpiece over the workpiece surface by means of one or more control axes of the machine, the focal length being variably adjustable by means of a variable optical unit. | 05-15-2014 |
20110087362 | MACHINING HEAD, LASER MACHINING TOOL, RECEIVING METHOD, MEASURING HEAD, MEASURING METHOD - A machining head of a laser machining tool includes a mechanical connector for connecting the machining head to a component of the laser machining tool, and a light path connector ( | 04-14-2011 |
20110000899 | CONNECTING PIECE, MULTI-AXIS MACHINING CENTER, ELASTICITY CONTROL METHOD - A connecting piece for a tool of a multi-axis machining center has a support on the machining center side, a holder at the tool side and a pushing device which elastically pushes the holder into a defined position against the support. The pushing force of the pushing device can be varied during the operation of the machining center. | 01-06-2011 |
20100176099 | METHOD AND DEVICE FOR THE INITIAL MEASUREMENT OF A WORKPIECE, AND THE PROCESSING OF A WORKPIECE - A method for workpiece levelling includes mounting the workpiece in a machine tool, measuring the position of the workpiece in the mounting and determining a translatory offset xv, yv, zv and a rotatory offset λv, βv, φv of the factual workpiece mounting compared to the ideal mounting from the measurement results and from a workpiece data forming an initial data set related to the ideal mounting, wherein for obtaining another initial data set a plurality of surface points of the mounted workpiece are measured in their position xn, yn, zn in space, the data of one of the initial data sets are varied a plurality of times in accordance with plural translatory and rotatory displacements for obtaining a plurality of varied data sets, from the varied data sets and their base data set the one data set is determined that represents a surface with a lowest deviation measure compared to a surface represented by the other of the initial data sets, and the translatory offset xv, yv, zv and the rotatory offset λv, βv, φv is determined from the translatory and rotatory displacement of the determined data set. | 07-15-2010 |

20100147815 | METHOD AND DEVICE FOR MACHINING A WORKPIECE - The invention relates to a method for machining a workpiece by means of a laser beam, wherein a laser beam is guided by a beam guiding device over the surface of the workpiece within a working window. The beam guiding device and the workpiece are arranged in such a way that they are movable relative to one another in a direction of displacement along a displacement section and that they can occupy a first and a second relative working position to one another. According to the invention, a point on the workpiece can be machined from the second relative working position, said point being located behind the point which is machined from the first relative working position when viewed in the direction of displacement. | 06-17-2010 |
