Natural fiber–reinforced composites: A review on material, manufacturing, and machinability (2019, background): “1 mm/rev: (a) chisel edge aggressive abrasive wear, (b) flank wear on the secondary cutting edge and rounding of corner of drill, and (c) adhesion of reinforcing fiber on the flank face of the drill.(124) Lotfi et al.”
Drilling on fiber reinforced polymer/nanopolymer composite laminates: a review (2017, background): “Abrasion is considered as chief tool wear mechanism during drilling on FRP as well as nano composite laminates and it can be occurred mainly on rake and flank face of the tool cutting edge causing severe abrasive wear on the flank face resulting poor structural integrity and long-term performance de”
Machinability study of glass fibre-reinforced polymer composites during end milling (2013, background): “Of all the conventional machining processes, studies on drilling of composite materials have received the most attention among researchers owing to the need for component assembly as well as to achieve delaminationfree composite materials [3–6].”
