Abstract

Laser beam machining (LBM) is the most common thermal energy-based non-contact, non-conventional machining process. The non-conventional manufacturing processes are used to remove extra material using a variety of mechanical, thermal, electrical, chemical, or combinations of these energies without the use of sharp cutting tools as is required for conventional manufacturing. With innovative approaches to manufacturing processes, it has transformed a number of industries. It is frequently used to machine a nearly complete classification of materials. The metal materials include carbon steel, titanium, stainless steel, copper, aluminum, and alloys of these metals, whereas a majority of non-metal materials are plastics, ceramics, rubber, and wood. A laser beam is directed during this procedure to melt and vaporize the undesirable material from the base material. This method works well for cutting geometrically challenging shapes. On sheet metal, a variety of machining operations, such as micromachining, cutting, and drilling, are readily and precisely performed. By examining several process parameters that have an impact on the quality characteristics, researchers have recently investigated a variety of strategies to enhance the performance of the LBM process The proper selection of material parameters (type, thickness, optical and thermal properties), operating parameters (assist gas pressure and cutting speed), and laser parameters (power, pulse width, frequency, modes of operation, pulse energy, wavelength, and focal position) can all greatly improve process performance, according to experimental studies. The primary factors influencing laser cutting quality are the laser power, pulse frequency, cutting speed, and focus location. In this paper detailed review of available literature is carried out to study the effect of LBM on different metallic materials like AISI 304, advanced high-strength steels (AHSS), EN43, mild steel, stainless steel, EN 1.4301, titanium alloy, alloy steels 1.4571, mild steel, alumina, and 22MnB5 steel
