Define laser beam machining. The laser stand for light stimulated emission of radiation. Laser head and tolerance. Laser beam machining working principle. Machines manufacturing electronics aeronautics etc. In this process a laser beam of high energy is made to strike on the workpiece the thermal energy of the laser gets transferred to the surface of the wp workpiece. Laser beam machining lbm is a form of machining process in which laser beam is used for the machining of metallic and non metallic materials. Plasma arc machining 1. Laser beam machining is a non conventional machining method in which the operation performed by the laser. A commercial laser for cutting materials involved a motion control system to follow a cnc or g code of the pattern to be cut onto the material. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The beam is emitted from whats called the laser tube and is reflected by several mirrors up into the laser head like a periscope within the head is a lens that finely focuses the beam onto the material surface for cutting or engraving. The process used thermal energy to remove material from a metallic surface. The processes can include laser drilling cutting grooving writing scribing ablation welding cladding milling and so on. At present plasma arc machining pam and laser beam machining lbm represents the most modern machining technologies used in the industry domains such as. Contents 2 introduction working principle of pam process details of pam applications of pam advantages of pam process disadvantages of pam process various types of pam processes conclusion references.
Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area. The laser optics and cnc computer numerical control are used to direct the material or the laser beam generated. A continuous cut is produced by moving the laser beam or workpiece under cnc control. Laser beam machining lbm is a non conventional machining manufacturing process a form of machining in which a laser is directed towards the work piece for machining. A co axial gas jet is used to eject the molten material and create a kerf. The working principle of laser beam.
