Laser Beam Machining Characteristics

Eds physical processes in laser materials interactions. The laser beam cutting process is characterized by large number of process parameters that determines efficiency economy and quality of whole process and hence researchers have tried to optimize the process through experiment based analytical and ai based modelling and optimization techniques for finding optimal and near optimal process.

Currently designed micro features on surfaces are being fabricated by mechanical micro machining ion and laser beam machining micro ecm electro chemical machining micro edm electro discharge machining and other methods as mentioned by wang et al. Investigation of effect of laser beam machining lbm process parameters on performance characteristics of stainless steel ss 304 mr. Thus these four properties of laser beam enable us to cut a huge block of steel by melting. 1983 characteristics of laser beams for machining. University kolhapur maharashtra india. In remote laser cutting the material is partially evaporated ablated by a high intensity laser beam allowing thin sheets to be cut with no assist gas. Molten metal which forms a layer of debris on the surface of the material during picosecond machining. The laser cutting process lends itself to automation with offline cadcam systems controlling either three axis flatbed systems or six axis robots for three dimensional laser cutting. Laser light has four unique characteristics that differentiate it from ordinary light. In laser beam welding or heat treating the instantaneous laser beam power per unit area. This parameter is key in determining the fusion zone profile area of base metal melted on a workpiece. Nato advanced study institutes series series b. Laser beam gaussian beam. 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.

They are also used for recording and reproducing large information on a compact disc cd. Among these technologies ultrashort pulsed laser ablation processes have gained. Laser beam is focussed for melting and vaporizing the unwanted material from the. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The high peak performance of our laser permits a maximum cut depth o. These are coherence directionality monochromatic high intensity. Yag and fiber lasers permit a controlled heat entry which is optimum for fine cutting. 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.
