Recent trends in laser assisted machining of ceramic materials

摘要： Machining of ceramics is difficult by conventional processes due to their hard and brittle nature as well as high costs involved. To overcome these disadvantages laser assisted machining (LAM) technique has been proposed. LAM has many advantages over conventional machining processes. LAM involves the use of a concentric beam of laser to heat and soften the work-piece thereby reducing its yield strength and increasing ease of machinability. With the progress of technology, numerous experiments involving LAM of ceramics have been performed and the effects of different machining parameters have been studied. In recent times, there have been various developments in laser technology, tools used and mechanisms of machining. This paper is intended to provide the elaborate literature review on the studies undergoing in LAM of ceramics and their comparison with conventional machining processes.
