Abstract: Modern composite materials constitute a significant proportion of the engineered materials market ranging from everyday products to sophisticated niche applications. While composites have already proven their worth as weight -saving materials, the current challenge is to make them machinable with minimum tool wear. In this study an attempt has been made to fabricate Glass fibre reinforced composites using hand moulding techniques and test its machinability based on delamination and tool wear using Ti-Nimate Coated Carbide and Ti-Carbonitride K10 end mill. The experiment was conducted in Vertical Machining Centre using Taguchi L8 orthogonal array. The test results showed that Ti-Carbonitride causes less damage to material during milling of glass fibre reinforced plastics (GFRP), whereas Ti-Nimate Coated Carbide has less tool wear at high speed, feed and depth of cut.

Keywords: GFRP; glass fibre reinforced plastics; composite milling; delamination; tool wear; solid carbide; tipped carbide.
