Laser Beam Machining Conclusion

Laser machining of composite materials requires short beam material interaction times short pulse and high scanning speed andor short wavelengths eg. 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 conclusion. Laser beam machining is a thermal machining process which uses laser beam to produce heat. But a laser also is capable of great damage to operators if the proper safety steps are not followed. Lasers are capable of cutting thin gauge metal and plate at incredible speeds and with outstanding results. Li in machining technology for composite materials 2012. Effect of laser beam on material 6 source. 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. Illustration of laser matter interaction and material removal of short pulsed laser beam machining is given. Laser beam machining used light energy from a laser to remove material by vaporization and ablation energy is concentrated optically laser emits either continuous or pulsed light beam 5 source. Laser beam machining lbm is a valuable tool for drilling cutting and milling of almost any material. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. 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. In this chapter a overview on nano second pulsed laser beam machining has been discussed. It is a non conventional machining process in which no tool is used. To keep everyone safe and the laser cutting machine operating a fabricating operation should have a safety program in place. Uv to minimise heat effects.

In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. It is used to machine both metallic and non metallic material. The mechanism by which a laser beam removes material from the surface being worked usually involves a combination of melting and evaporation although with some materials such as carbon and. Difficulties of pulsed laser ablation is discussed.
