In this study, Taguchi and ANOVA optimization was employed to analyze the
micro-drilling of cellulosic-based fiber reinforced composites. These
composites were micro drilled and the analysis of composites focused on
overcut, hole damage factor (HDF), and taper ratio. Micro-holes were drilled on
plates with thicknesses of 4 mm using a Taguchi orthogonal array (L27) design.
ANOVA and Taguchi analysis revealed that tool diameter significantly impacts
overcut and taper ratio in composites. The hole damage factor (HDF) was found
to be primarily influenced by spindle speed. Tool diameter also influences the
overcut and taper ratio by 60%, and 47%, respectively. The effect of spindle
speed on HDF was determined to be approximately 65%. Spindle speed is the
second most influential parameter for overcut and taper ratio, while feed rate
is the least influential. For HDF, feed rate is the second most influential
parameter, while tool diameter is the least influential. The optimum
combination of control factors A1–B2–C1 (0.4 mm – 7500 rpm – 0.3 mm/min) was
determined to minimize overcut, HDF, and taper ratio in the drilling process. These
results provide the industry with valuable data that can potentially be
utilized to manufacture high-quality micro-drilled cellulosic-based fiber
reinforced composites while potentially
reducing production costs.
