Abstract

Laser cutting is a processing technique based on the theory of excited radiation. Almost all materials can be cut using a laser. Sharp-edged and straight shapes and patterns with high precision and dimensional accuracy can be created. Since mechanical forces do not occur in laser cutting, fast and vibration-free cutting operations can be performed. It is preferred in many areas in the industry as it is effective for obtaining dimensional accuracy and precise tolerances. There are some independent variable parameters used in laser cutting that affect the product quality. These are important process parameters such as laser power, cutting speed, focal distance, nozzle diameter, pulse frequency, pulse energy, focal point position, sheet thickness, assist gas type, and pressure. These process parameters significantly influence the material removal rate, surface roughness, kerf width and kerf taper, which are the dependent variables or the experimental outputs. Therefore, the degree of performance of these outputs is measured by controlling the independent variables. In this chapter, these outputs in terms of machining efficiency are revealed in detail
