A Review of the Machining Process Parameters for Natural-Fiber-Reinforced Composites

Abstract

The important properties of natural composites include but are not limited to their strength-to-weight ratio, durability and biodegradability. Natural composites are inhomogeneous by nature; drilling operations are difficult because the drill bit must alternately pierce through the layers of the matrix and fibers. This may cause delamination, fibers are pulled out and the matrix breaks, etc. In numerous types of research, it is seen that the spindle speed, drill diameter and drill geometry greatly influence the delamination factor and feed rate, affecting the surface roughness. In this review, the impact of the drilling and milling parameters on various natural-fiber-reinforced composites are taken into account and assessed.
