Laser Beam Machining Surface Finish

Laser beam is focussed for melting and vaporizing the unwanted material from the parent material. It produces monochromatic light which is in the form of an almost collimated beam that can be focussed optically on to very small spots of less than 0002 mm dia.

Laser beam machining is a thermal machining process which uses laser beam to produce heat. Pulsed mode co 2 laser cutting gives better surface finish than. 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. The latter is a. Surface roughnesses in the direction of the laser beam fand that in the direction perpendicular to the laser beam axis that is in the cutting direction. This paper develops the predicting model on surface roughness of laser beam cutting lbc for acrylic sheets. In this post you learn what is laser beam machining its working principle parts advantages applications and limitations. 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 machining process metal is removed by melting and vaporization of metal particle from surface of work piece. Research papers available on laser beam machining on the various properties that affect the quality of the process such as heat affected zone formed. Today we will learn about laser beam machining principle working equipments application advantages and disadvantages with its diagram. The former is of no crucial importance in considering the problem of the cut surface roughness due to the fact that the laser is applied to thin sheet cutting. The focused laser beam is directed at the material which then either melts burns vaporizes away or is blown away by a jet of gas leaving an edge with a high quality surface finish.

Research on surface roughness by laser cut. The high frequency of monochromatic light will fall on the surface then heating melting and vaporizing of the material take place due. Box behnken design based on response surface method was used to predict the effect of laser cutting parameters including the power requirement cutting speed and tip distance on surface roughness during the machining.
