| Abstract: | Drilling is one of the important machining processes in hole making
operations. Delamination is a vital problem during any drilling operation. It
causes structural integrity reduction and poor assembly tolerance as well as
potential for long-term performance deterioration. As a result, drilling of any
material requires dimensional stability and interface quality. In this study,
glass fibre reinforced plastic composite is selected as experimental material
for investigation of cutting parameters (cutting speed, feed rate and tool
geometry) affecting delamination in drilling operation. Moreover, the Taguchi
method is used to determine optimal cutting parameters for damage-free drilling
material. A plan of experiments, based on L’16 Taguchi design method, is
performed drilling with cutting parameters in a GFRP composite. The orthogonal array, signal-to-noise (S/N) ratio and
analysis of variance (ANOVA) are employed to investigate the optimal drilling
parameters of GFRP composites using four different drills. The experimental results demonstrate that the feed
rate is the major parameter among the controllable factors that influence the
delamination. Additionally, the optimal combinations of the cutting parameters are
determined. |
