Аннотация:Now a day, Glass Fibre-Reinforced Plastics (GFRP) are being widely used in diversity of engineering applications in many different areas such as aerospace, automotive and aircraft industries due to their light weight, high modulus, high specific strength and high fracture toughness.Drilling or Milling of GFRP composite material is a rather complex task owing to its heterogeneity and the number of problems, such as surface accuracy and delamination of drilled holes, which appear during the machining process, associated with the characteristics of the material and the cutting parameters.Current paper focuses the investigational details to find out roughness on drilled hole in GFRP composite laminates by using Taguchi's DOE L9 orthogonal array.The main objective of the present work is to optimize the process parameters in the drilling of GFRP composite using Taguchi DOE and to find the significance of each process parameter using ANOVA.As far as the effect of input factors are considered, the factor spindle speed is having significant and dominating effect on GFRP composite material.
