The purpose of this experimental work is to optimize the process parameters on cutting stainless steel by laser beam machining technology.

Laser beam machining process parameters. Abrasive jet machining ajm. Laser beam machining lbm and 4. The laser cutting process uses a focused laser beam and assist gas to sever metallic plate with high accuracy and exceptional process reliability. Plasma arc machining pam. 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 a novel thermal energy based advanced machining process which can be used for machining a wide range of materials. Advanced manufacturing processes by dr. Advantages of laser cutting over mechanical cutting include easier workholding and reduced contamination of workpiece since there is no cutting edge which can become contaminated by the material or contaminate the material. Advantages of laser technology. Laser beam welding. The identified cutting parameters during experiments were cutting speed v frequency f and duty cycle d and the output response was surface roughness. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. Process variables in laser cutting are discussed. The laser beam is generated by a resonator and delivered through the cutting nozzle via a system of mirrors. 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 material to be cut is locally melted by the focused laser beam. Hence the characteristic of non contact between the tool and the. Abstract laser beam machining lbm is one of the most widely used thermal energy based non contact type advance machining process. L 27 orthogonal array design was selected for full factorial design to better understanding of interaction between process parameters. In ajm the material removal takes place due to the impingement of the fine abrasive. Precision may be better since the laser beam does not wear during the process. Therefore this experimental work discusses on the optimization of laser cutting parameters on stainless steel because stainless steel is widely applied in industries. And also learn about unconventional machining process characteristics of unconventional machining process and classifications of unconventional machining processes. Laser technology has the following advantages. 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. Electron beam and plasma welding processes duration. Multi objective optimization of laser beam machining process parameters pj.
