    ABSTRACT:
    Composite materials are the emerging material for enormous applications in various engineering domains in place of conventional material, due to its extremely high strength to weight ratio and corrosion resistance properties. The composite laminates are difficult to machine materials, which results into low drilling efficiency and drilling induced delamination. These problems can affect mechanical properties of produced parts, therefore, lower reliability. Drilling is a widely used technique to assemble components specifically, in more complex structures. This paper presents the experimental characterization to understand the effect of cutting parameters used for drilling holes on the thrust force, delamination extent, and hole surface roughness using two-flute solid carbide twist drill of diameter 6.35mm. It also describes the identification of critical thrust force below which no damage occurs. Results show that the feed rate plays dominant role in delamination, thrust force and hole surface roughness than the spindle speed.
