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. CO_2 and Nd:YAG lasers are mostly used for industrial purposes. Drilling, cutting, grooving, turning and milling are the ...
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...
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...
1. A method for machining workpieces in a machining zone by means of a laser beam wherein IL=laser intensity value, IC=lower laser intensity value where abnormal absorption .perspectiveto.1, ID=critical upper limiting laser intensity value, at which shielding of the workpiece by a plasma is ...
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....
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...
A beam bender for changing the direction of a laser-beam in a laser- beam machining apparatus which comprises a base (1), a flange (2), a light-guide member (5), and a mirror holder (6) housing a bender mirror (7). Depending on the direction from which the laser beam is applied...
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...
