        abstract = {Although metal cutting operations traditionally employ mechanical or manual processes, laser cutting can be a viable, effective, and cost-efficient option for metal fabrication. Laser equipment is distinct from other cutting machines in both design and application. For example, laser cutters do not make direct contact with material, rely on high-energy power sources, have tighter cutting tolerances, and are generally automated to maximize precision. A laser device fires a concentrated stream of photons onto a precise area of the work piece in order to trim excess material and shape the work piece into a specific design. These machines are highly effective in cutting various grades of steel, such as stainless and carbon steel. However, lasers are less efficient on light-reflective or heat- conductive metals, like aluminum or copper, and require specific modifications to shape these materials. The material being cut often dictates the type of laser used in fabrication, making it important to match equipment specifications with forming stock.
This project deals with the cutting parameter of Nd-yag laser cutting of stainless steels. steel sheets to be cut satisfactorily by a pulsed Nd: YAG laser at the optimum process parameter ranges. In this project we will be made three attempts for made test pieces to predict the surface quality and dimensional accuracy of Nd-yag laser cutting for getting maximum best mechanical properties and min HAZ with various gases pressure. The responses considered are the heat-affected zone (HAZ) and mechanical properties analysis. The effect of the process parameters on the output responses is also investigated through mechanical properties and micro structural analysis.},
