Effect of Fiber Laser Parameters on Kerf Properties in Cutting Operations

In recent years, the widespread use of type 201 stainless steel has been due to its high specifications, including strength and corrosion resistance. Despite its excellent properties, this metal may be affected during cutting operations. One of the best methods used for this purpose is laser cutting. This study examined the impact of various fiber laser cutting parameters on the properties of 201 stainless steel to achieve optimal cutting results. Different thicknesses, cutting speeds, and power levels were employed, with a focus on assessing upper and lower kerf widths and vertical deviation. A total of 27 practical experiments were conducted using a Taguchi L27 design and predictive analysis with the “Minitab” program. The results were promising, revealing that the most influential factors on upper and lower kerf widths and vertical deviation were thickness and cutting speed, while the effect of power was relatively minor. Ultimately, the goal of this research was to achieve the narrowest upper and lower kerf widths and minimize vertical deviation—a step toward improving the fiber laser cutting process for type 201 stainless steel.
