Abstract
Laser beam cutting is one of the important advanced machining processes. It is gaining importance over conventional machining methods due to its superior characteristics. However, significant future attempts are still required to overcome the challenges as regards to use laser beam cutting in different environment and for various materials. This paper provides a review on laser beam cutting where introduction, salient features, and past work are discussed. It starts with an introduction to the process where laser system and its components, working principle and mechanism, and important process parameters are discussed. Review of past work under various categories on laser beam cutting is followed. Paper ends with summary and important future research directions to establish the field further.
