A REVIEW OF LASER ASSISTED MACHINING AND BENEFITS

ABSTRACT

The use of high strength materials, such as nickel-based superalloys and titanium alloys, is becoming increasingly common in aerospace, automotive, energy, medical, and mining applications. However, these materials are traditionally considered to be difficult-to-machine. Conventional machining processes for these materials are notoriously affected by slow machining speeds and/or frequent tool changes due to short tool lives. Laser-Assisted Machining (LAM) has begun to emerge as a viable industrial option for machining of difficult-to-machine materials. Laser machining is the technique in which machinability of hard to cut material can be improved. Present Research Work is to revive and collect the use of laser assisted machining for hard to machine material, advantages and problems coming during this hybrid machining A large amount of work has already been done on LAM to increase the tool life, cutting forces, residual stresses, cutting temperature and surface finish.Hard to cut alloys like as Tiand Ni are broadly used in medical, nuclear, shipping and aerospace industries due to its properties. In day today researches, researchers paid a lot of attention on improving the machinability of this material more effectively by using any external energy assisted machining. The current research paper is a review paper on laser assisted machining to find the useful outcomes using different techniques on different material. Results coming out of laser assisted machining are also been compared to conventional machining in this present paper.
