moreFiber reinforced composites are used in many engineering applications because of their low strength to weight ratio. Delamination is one of the major problems in manufacturing field for using composites as a raw material. In this work, the delamination of basalt fiber reinforced composites was studied with the effect of coolant in drilling operation. The three set of Basalt fiber reinforced composites is prepared by using hand layup techniques with Vetiver and vinyl ester at varying composition. Taguchi design of experiment was used to investigate the effects of drilling parameters such as spindle speed [2500, 2750, 3000 rpm], feed rate (0.2, 0.4, 0.6 mm/rev). A series of experiments based on L9 orthogonal arrays are conducted using CNC machine for both with the coolant and without the coolant and resulting delamination factor was determined. It was observed that speed is highly influencing parameters than feed rate for the delamination of the basalt fiber reinforced composites when the coolants were not employed. The delamination is very less even at the high speed and feed rate when the coolants were employed for all the three varying compositions made.
