| Summary: | As the goal for aircraft weight reduction and low fuel consumption becomes a dire
concern in aerospace industries, there is driving desire for the increasing use of advanced exotic
materials such as composites, titanium and Inconels in the aerospace industry because of their high
strength to weight ratio. Nevertheless the inherent anisotropy, inhomogeneous properties of CFRP
and low bonding strength within the laminates make machining of these composite materials results
in several undesirable effects such as delamination, micro-cracking, burr, fiber pull out and
breakage. This paper discusses an experimental investigation into the influence of machining
parameters on surface roughness when milling CFRP using 4 mm-diameter 2-fluted carbide endmill
coated with Titanium Aluminium Nitride (TiAlN). Relationship between the machining
variables and the output variables is established and a mathematical model is predicted for the
surface roughness produced during the milling process for the machining conditions investigated. |
