Optimization of Kerf Characteristics During Micromachining of Nickel-Based Superalloy

To optimize the machining process for materials like Inconel-718, it's important to carefully analyze the machining settings. Determining an acceptable ideal range for cutting parameters is crucial for achieving high-quality cuts, presenting a challenging aspect in this field. The objective of this work is to develop a reliable model capable of recommending the appropriate range of variables. Experiments by a solid state (Nd:YAG) laser for cutting operation on thick sheet size 1.4 mm were carried out in present study. The experimental data was then employed to develop models mathematically. A multi-objective evolutionary algorithm was used to optimize the created models, and an optimal parameter range was identified. Finally, the acquired range was confirmed through additional testing. The obtained cutting range was found to be substantial based on the results.
