Selection of optimal machining conditions for the composite materials by using Taguchi and GONNs.

Highlights: [•] Increasing the number of flutes (cutting edges) improved the surface quality. [•] The recommended tool had 4 flute and the estimated surface roughness was 1.6586μm. [•] Minimum surface roughness was 1.626μm with a 4 flute end mill. [•] Optimal cutting parameters were obtained 113m/min, 0.04mm/rev, and 3mm. [ABSTRACT FROM AUTHOR]
