GFRP composites find diverse applications in many engineering fields. For certain applications, the use of composites rather than metals has in fact resulted in savings of both cost and weight. The usage in many fields demands several machining operations to be performed on GFRP composites. As such, the present paper investigates the effect of cutting force in the turning of GFRP pipes using CBN tools. Experiments are conducted on a lathe using the central composite design technique. A model is developed to correlate the cutting parameters with cutting force, using response surface methodology. The results indicate that the developed model is suitable for prediction of cutting forces in turning of GFRP composites. The effect of different parameters on cutting forces are analyzed and presented in this study.
