Laser beam machining case study. When controlled by a. In this chapter a overview on nano second pulsed laser beam machining has been discussed. As well as for cutting. 752 material removal mechanism of nanosecond pulsed laser beam cutting at submerged condition. Provided by a specific organisation each case study describes one or more laser applications for the manufacture of a particular component. Motion of the laser beam. Today we will learn about laser beam machining principle working equipments application advantages and disadvantages with its diagram. In this machining process metal is removed by melting and vaporization of metal particle from surface of work piece. The term laser originated as an acronym for light amplification by stimulated emission of radiation. To improve the wetting quality of water film on workpiece surface organic additives are added. A laser beam has the special property that the light waves emitted are all in step with one another coherent and usually of one wavelength or colour. Neverthless on the fly laser machining offers the ability to. A parametric study on laser beam cutting of inconel 625 superalloy at submerged condition has been carried out. Sometimes water solution of salts or bases or acids are used during submerged laser beam machining to improve the etch rate and finish quality. Underwater pulsed laser beam cutting with a case study.

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. 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. Illustration of laser matter interaction and material removal of short pulsed laser beam machining is given. Laser beam machining is a thermal machining process which uses laser beam to produce heat. These case studies show the benefits that can be gained and are all derived from practical situations within industry. Mitra in microfabrication and precision engineering 2017. This process uses thermal energy to remove material from metallic or nonmetallic surfaces.
