Abstract
The present work focuses on the laser turning of Alumina (Al 2 O 3 ) ceramic materials and to analyze the effect of various machining input parameters. The design of experimental trials based on the Taguchi technique and the experimental process input values are considered such as pulse frequency, workpiece rotational speed, laser beam average power, and constant feed rate. The optimum process parametric settings are identified for the output parameters of surface roughness (R a ) and Material removal rate (MRR). The output responses are analyzed based on the signal-to-noise ratio. Based on the experimental study, the better surface roughness (R a ) is achieved as 2.37 µm for the input response combination of A 1 B 1 C 1 . Similarly, the Material removal rate is achieved as 0.79 mm 3 /min for the combination of A 1 B 1 C 3 .
