Material Removal In Laser Beam Machining

Laser material interactions a great advantage of laser machining is capability to machine any kind of material not necessarily conductive depending on laser intensity and interaction time. 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.

Any solid material which can be melted without decomposition can be cut with the laser beam.

Material removal in laser beam machining. Advantages of laser beam machining. Working of laser beam machining process. Mrr cl lp ev abh. Though lbm is not a mass material removal process it is possible to use this process in mass micro machining production. Its one kind of non traditional or advanced manufacturing processproduction of laser beam and with the use of lasers how can material can be removed is to be explained over here. Lec 15 laser beam welding duration. 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. Laser beam machining is a thermal energybased advanced machining process in which material is removed by focusing the laser beam on the work surface at a constant distance to melt and vaporize the unwanted work material. 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 nptelhrd. Joining technologies for metals 7941 views. Material removal mechanism in lbm machining by laser occurs when the power density of the beam is greater than what is lost by conduction convection and radiation and moreover the radiation must penetrate and be absorbed into the material. In contrast to some other processes laser operates using high energy photons therefore there is not a typical tool as the laser beam directly targets. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The main advantages of laser beam machining are ease of automation for complex cutting patterns absence of tool wear and.

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. Other major advantages of the laser beam machining include the following. The machining rate mmmin can be described as follows.
