Process Characteristics Of Laser Beam Machining

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. Laser beam gaussian beam.

Laser Beam Machining Non Traditional Machining

In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece.

Process characteristics of 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. Hence the characteristic of non contact between the tool and the. To relate the operating variables and characteristics of the laser to the parameters affecting the cut quality many models for the laser machining process have been developed over the years. It is used to machine both metallic and non metallic material. The lens is defined by its focal length which is the distance from the lens to the focused spot. 1983 characteristics of laser beams for machining. Laser beam is focussed for melting and vaporizing the unwanted material from the parent material. This study investigates the influence of laser beam machining lbm process parameters on surface roughness and kerf width while machining stainless steel ss 304. 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 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. 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. 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. Laser beam machining lbm is a non conventional process in which material removal takes place through melting and. 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.

Laser beam machining is a thermal machining process which uses laser beam to produce heat. Laser beam machining lbm is a novel thermal energy based advanced machining process which can be used for machining a wide range of materials. Nato advanced study institutes series series b. Eds physical processes in laser materials interactions. It is a non conventional machining process in which no tool is used. As yilbas and kar first reported in 1998 in the co 2 laser gas assisted cutting process modeling of an interaction mechanism is important 28. 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.
