However, it is now facing several challenges such as rapid product development, flexibility, low to medium volume, and low-cost production. Many advanced/unconventional technologies/tools are being developed worldwide to face these challenges. Among these technologies laser has become quite popular due to its ability for precise focusing and ease in controlling the heat source. Researchers worldwide are now focusing their attention on improving productivity and product quality in the application of laser technology for the manufacture of components required for consumer electronics, aerospace systems and vehicles, bio-medical instrumentation, automobiles, and shipbuilding applications.
