Advantages of laser technology.

Process parameters in laser beam machining. The material to be cut is locally melted by the focused laser beam. Laser technology has the following advantages. The laser beam is generated by a resonator and delivered through the cutting nozzle via a system of mirrors. The obtained nearest dimensions with our designed dimensions of the shape the input parameters ie power and scanning speed are 3 kw and 50 mms. Intense laser beam on the work piece. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. The lens is defined by its focal length which is the distance from the lens to the focused spot. Process variables in laser cutting are discussed. Rayate pg student kkwagh institute of engineering education and research nasik maharashtra india. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The heat of the laser beam subsequently heats melts and evaporates the work piece material as this process does not need the cutting tool so no mechanical force is exerted on the work piece thus work piece does not need to be clamped like in conventional machining process 3. 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 process a laser beam is focused for melting and vaporizing to remove material from the workpiece as per the desired shape 1. Laser beam cutting lbc process has a wide range of applications in different manufacturing processes in industry due to its advantages of high cut quality and cost effectiveness through mass production rate 1. The identified cutting parameters during experiments were cutting speed v frequency f and duty cycle d and the output response was surface roughness.

Hence the characteristic of non contact between the tool and the. The laser cutting process uses a focused laser beam and assist gas to sever metallic plate with high accuracy and exceptional process reliability. Laser beam machining lbm is a novel thermal energy based advanced machining process which can be used for machining a wide range of materials. Abstract laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process. From the above set of observations and results it was concluded that laser beam machining is suitable machining process for the micro elliptical profile in aluminium composite material. Multi objective optimization of laser beam machining process parameters pj. Laser beam machining is a thermal machining process which uses laser beam to produce heat. The laser cutting process involves focusing a laser beam usually with a lens sometimes with a concave mirror to a small spot which has sufficient power density to produce a laser cut.
