Abstract: Pulsed laser drilling is used to produce bore holes having a small diameter, for example, in hollow workpieces. Turbine blades, e.g., have a multitude of fine cooling air bore holes, which are able to be produced by this method, e.g., with high positional accuracy and in an automated manner.A checking method is provided by which drilling faults, e.g., with regard to piercing and bore-hole geometry, may be detected in a more reliable manner.A method is for checking a bore hole introduced in a workpiece by laser pulses, in which characteristic signals from the area of the bore hole are received with the aid of a sensor and compared to setpoint values and only signals received in a characteristic time interval following a laser pulse are taken into account.

Abstract: A pulsed machining method for the optimized machining of a contour which is characterized in that the instantaneous frequency ratio of φ of the pulse frequency of tool fL and of the rotational frequency of tool fCNC is optimized to achieve a highest possible degree of coverage of the individual machining pulses in the context of a shortest possible machining duration and without a direct concatenation of the machining pulses. It is especially preferred that this be achieved in that frequency ratio φ is an irrational number, thus cannot be expressed by the ratio of two whole numbers. By applying the method according to the present invention, a considerable time savings is achieved since there is no longer a need for time-consuming preliminary trials to ascertain an at least sufficient frequency ratio φ.

Abstract: A method for optimized milling of workpieces close to the final contour, in particular chamfers on turbine blades, is disclosed. The method is characterized in that a numeric optimization method is provided for the automatic control of the kinematic sequences of motion, wherein an additional rotation around an axis parallel to the tool axis is optimized in terms of kinematic and/or kinetic and/or workpiece-specific manufacturing criteria. With the method, it is possible to achieve optimum results in the milling of chamfers close to the final contour or in the deburring of workpiece edges. In this case, the method makes it possible in particular to make available a path optimization that is required in order to achieve an optimum processing result, wherein this optimization is preferably automated and can take place within a short time. In addition, the inventive method achieves a high level of series stability in manufacturing.

Abstract: A method and device for producing a hole in an object is disclosed. The method includes the generation of a beam for removing material such that a bottom of a borehole is placed in a focus position of the beam, and a removal of material by impingement of the beam on the bottom of the borehole. A repeated placing of the bottom of the borehole in a focus position of the beam in order to compensate for the increased depth of the hole as a result of the removal of material is combined with a step of changing a radiation characteristic of the beam when the bottom of the borehole is repeatedly placed in a focus position.

Abstract: The invention relates to a process and an apparatus for automatic laser focusing. The core concept of the process is the automatable and especially preferably the automated photographing of the focal spot generated during a focus series by camera and a determination of the particular focal spot diameter as well as an evaluation of this data by an interpolated or approximating function that allows a conclusion about the focal spot with the smallest focal spot diameter and thus with the associated optimal focal distance. A series of disadvantages present in the state of the art can be avoided by using the process in accordance with the invention, in particular the great expenditure of time in the determining of the optimal focal distance and the uncertainty in the selection of the optimal focal spot associated with an operator are eliminated in the framework of the photographing of a focus series.

Abstract: A method relating to near-net-shape machining of curved contours such as those occurring, for example, in the fabrication of blades for propulsion engines and the like is described. Accordingly, the shape error in curve grinding is minimized by suitable compensation functions, in particular by interpolating and approximating cubic splines. The present method minimizes the number of tests required to set up a grinding machining operation and thus the number of semifinished products required to do so. At the same time, rejects in fabrication of curved workpieces are reduced by increasing the machining quality. The use of complex chucking devices is avoided and cutting performance is maximized.
