1.1 Laser Cutting Process Laser cutting is a non-conventional machining process that uses a laser beam to cut material. The laser beam is focused onto the material and melts or vaporizes it, leaving a clean, precise cut. Laser Beam Cutting (LBC) has become the predominant method for cutting various types of sheet materials in industries today. This advanced technique offers the ability to cut a wide range of materials, including metals, composites, and ceramics. By delivering thermal energy through a focused laser beam, the material is heated and subsequently cut. This unique process eliminates the need for mechanical cutting force, tool wear, and vibration, making LBC ideal for cutting even hard or brittle materials. The laser beam interacts with the electrons of the material, causing some of the energy to be absorbed. This absorption results in a localized increase in temperature, which can lead to melting, vaporization, or a change in the chemical state of the material.

1. INTRODUCTION Laser cutting is basically a CNC cutting process in which a high-powered laser is used to cut through materials as per design data. In this process, a high-density light beam is generated by stimulating lasing material with an electrical discharge, within an enclosed container. Laser cutting has become an increasingly popular method for cutting materials such as metal, plastic, wood, and glass. A wide variety of industries, including automotive and medical device industries use laser cutting because it offers a high degree of accuracy and precision.
In cutting, a pressurized gas is used to remove the molten material from the groove. The type of auxiliary gas employed depends on the material being cut. Inert gases are used to protect the surface from oxidation, while active gases (usually oxygen) generate an intense exothermal reaction, further increasing the temperature in the cutting area.
Industry have used the set process parameters like gas pressure, cutting speed, stand-off distance, etc. to manufacture a different job of different material in laser cutting machine. In this research work, the analysis of jobs were performed by changing the laser cutting parameters and try to optimize it, which could help the industry to improve its operation and processes. Optimization in process parameters of laser cutting machine will affect the
