Piercing of Epoxy Laminates with Wood Drill Point Geometry

The through hole in composite laminates is done by piercing, which is one of the most essential procedures. The piercing of epoxy laminates results in significant impairment to the area around the hole that is pierced. The improved drill geometry allows for the creation of holes that are free of burr formation. The current study effort is centered on wood drill as a potential factor that affects the forces that are applied during piercing. When piercing in composite materials, the wood drill shape allows for more precise piercing. The penetration of wood drill configuration on the laminate is significantly different, and as a result, it influences the burr formation that is caused by piercing. According to the findings of the experiment, there seems to be a significant relation between the feed velocity and axial forces induced in epoxy laminates.
