Laser beam machining (LBM) is one of the most widely used thermal energy based non-contact type advance machining process which can be applied for almost whole range of materials. Laser beam is focussed for melting and vaporizing the unwanted material from the parent material. It is suitable ...
ReviewLaser beam machining (LBM) is a widely used thermal advance machining process capable of high accuracy machining of almost any material with complex geometries. CO2 and Nd:YAG lasers are mostly used for industrial purposes. Drilling, cutting, grooving, turning and milling are the applications...
This invention relates to an method and apparatus for machining workpieces by means of a laser beam. In the case of this type of machining of workpieces, the laser irradiation, by means of an optical system, is focussed on the workpiece and absorbed at its surface. The resulting heat is ...
1b). The scanning speed of the beam was changed in a horizontal axis. The laser spot size on the sample was changed in the vertical axis of the array by controlling the elevation position z of the sample. The variable spot sizes provided different laser fluences. The path of the scanned...
PURPOSE:To cut the mild steel by the laser beam at high speed and with excellent quality in the laser beam machining method where the laser beam is converged, and a work is irradiated with the laser beam to perform the laser beam machining. CONSTITUTION:The dissimilar material to be cladded...
摘要: PROBLEM TO BE SOLVED: To provide a calibration method of a laser beam machining apparatus capable of calibrating a laser beam machining apparatus without forming any machining trace on a workpiece with high accuracy, and the laser beam machining apparatus....
PROBLEM TO BE SOLVED: To provide a laser beam machining method for welding or soldering a land part of a bar-shaped projecting part and a laser beam machining device for the method. SOLUTION: Laser beam emitted from an optical fiber connector 11 and collimated by a pair of collimation lenses...
PURPOSE:To make it possible to machine 1 material having machining difficulty due to the high hardness highly efficiently by additionally performing mechanical machining to the fragile part caused by preillumination of laser beam. CONSTITUTION:A workpiece 1 is made to run in the direction of arrow ...
Laser beam machining (LBM) is a thermal energy based advanced machining process in which the material is removed by (i) melting, (ii) vaporization, and (iii) chemical degradation (chemical bonds are broken which causes the materials to degrade). When a high energy density laser bream is focu...
Laser ablationoccurs when high fluence, short wavelength laser radiation interacts with attenuating materials. A problem that dogs laser ablation machining in the industrial theatre is debris: solid, melt and vapour are all generated. This is a problem borne of micro–particulate debris and van der...
