Drilling of polymer matrix composites: A review (2013, background): “observed that drilling at high spindle speed leads to reducing the thrust force owning to the decreasing the cutting resistance of epoxy, while the surface roughness improved due to the smearing effect of fiber particles and matrix at the higher temperature.(19) When the temperature rise exceeds the”

Natural fiber–reinforced composites: A review on material, manufacturing, and machinability (2019, methodology): “It was found that optimum cutting values of parameters in drilling of coir fiber–reinforced composites using Nelder–Mead and genetic algorithm methods are lower drill bit diameter, lower speed, and moderate feed rate.(90,151) Accordingly, an increase in the flank wear results in a significant raise ”
