Abstract - Laser Beam Machining is a type of modern
milling,its major application is in the cutting of metallic and non- metallic sheets.
machining process which includes the use of LASER (Light Amplification by Stimulated Emission of Radiation)to remove the material from the surface of a workpiece. The motive behind choosing this topic as a subject of studyis to understand modern machining trend and use of some modern technologies for research regarding development in the field. First, various research papers of many known authors in the field are studied thoroughly. Then experiments are carried out after selection of material for the research. Finally modern and advanced tools utilized to explore results of experiments in the virtual environment. The experiments have been carried out considering various parameters necessary in the field of Laser Beam Machining. One of the key LBM processes which are extensively used in the industry i.e., Fiber Laser Machining are selected for the purpose of the study. Then the results of experiments will be fed to a DOE (Design of Experiments) tool to analyze the results from the experiments and compare them.
1.1 Types of leasers Solid State lasers and Gas Lasers are two types of lasers used in machining applications. Nd:YAG lasers, Fiber lasers, Diode lasers, and Ti: Sapphire lasers are the different types of solid state lasers. Solid state lasers are categorized as lamp pumped and diode pumped depend on the type of energy source used for excitation CO2 Lasers, Excimer Lasers, and Copper Vapour Lasers are the three types of gas lasers used in machining. Lasers are categorized as Continuous Wave (CW) and Pulsed Wave (PW) based on their wave properties.
1.2 Principle of LBM Melting, vaporization, and chemical degradation are all stages of the material removal mechanism during LBM. When a laser beam with a high energy density is focused on the work surface, the work volume is heated and transformed into a molten, vaporized, or chemically altered state as the thermal energy is absorbed, that can be easily removed with the helpof a high-pressure assist gas jet.
Key Words: Condition monitoring, Tool Wear, Surface Roughness, Vibrations, LBM, DOE, Reduction in bur formation.
1.INTRODUCTION
1.3 LBM Variation
The use of traditional machining technologies is limited due tothe emergence of innovative engineering materials, severe design requirements, intricate shape, and unusual size of workpiece. As a result, it was decided to design some advanced machining processes (AMPs), which are nonconventional machining procedures. Numerous advanced machining processes (AMPs) are used in today's industry, but each has its own set of constraints in terms of workpiece material, shape, and other factors. Advanced machining processes are beam machining processes, jet machining processes, electro discharge machining, ultrasonic machining . Laser Beam Machining (LBM) is a cutting technique that is used to shape a wide range of engineering materials. cutting, drilling, marking, welding, sintering and heat treatment are just a few of the applications for laser beams. Although the laser can be used for turning and

Drilling (1-D), cutting (2-D) and grooving, turning and milling (3-D), and micromachining of various workpiece materials are the most common LBM configurations. For drilling hundreds of closely spaced holes in structures, laser beam drilling has become the acknowledged and cost effective method. Trepan and percussion laser beam drilling are two forms of laser beam drilling. Trepan drilling entails cutting all the way around the hole's circumference, with no relative movement of the laser or workpiece, percussive drilling ‗punches' directly through the workpiece material. The reduction in processing time is a natural benefit of the laser percussion drilling method.
