Drilling of composite material is more complex than conventional drilling, as material removal of isotropic material is uniform than composite material. The cutting edge of drill bit will damage the composite material and removes the fibre in indefinite manner. Improper holes in composite material will cause improper assembly and even can cause premature failure of components made with composite material such as CFRP, Carbon fibre, glass epoxy. By estimating optimal machining parameter such as Feed rate and cutting speed, machining of improper holes in composite material can be eliminated. Optimal machining parameter can be estimated by simulation of composite material. Simulation is performed with help of Abaqus/Explicit software from Simulia.
