Abstract: The present research work concentrates on the development of partially bio-degradable coconut-husk fibre reinforced plastic (CFRP). Drilling was performed on the developed CFRP with different kinds of drill geometries. Residual tensile strength was then determined on the drilled specimens. The input parameters while drilling were drill tip geometry, spindle speed and feed rate. Box-Behnken Design (BBD) has been used for the planning of experiments. Mathematical modelling for the residual tensile strength takes place through response surface methodology and for the best individual process parameters genetic algorithm approach has been adopted. The maximum value of residual tensile strength was observed at jodrill type of drill tip geometry. Confirmation experiments indicate that predicted and actual value of residual tensile strength are at close agreement.
