| Summary: | The demand of the Carbon Fiber Reinforced Polymer
(CFRP) has been significantly increasing over the years
especially in automotive and aerospace since CFRP
possesses an excellent strength-to-weight ratio. However,
milling CFRP challenging due to its anisotropic and
heterogeneous property therefore produce brittle and
dust-like chips. As CFRP is a combination of layers of
carbon fibers embedded in matrix resin, machining
process must be conducted below the glass transition
temperature (Tg) of the matrix resin as it can degrade the
CFRP. In this experimentto investigate the effect of cutting
speed and cutting conditions on the tool wear during the
milling process, CFRP was machined with 6mm diameter
uncoated tungsten carbide tool with helix angle of 30°.
Milling of CFRP was performed with three cutting speeds
of 130, 150 and 170 m/min in three different cutting
conditions which is dry, coolant and chilled air with
constant feed rate of 2100 mm/min and depth of cut of 2
mm. The highest average tool wear of 110 μm was
obtained during milling the CFRP with cutting speed 170
m/min in chilled air condition, 25.5% higher than the
average wear of 82 μm at low cutting speed of 130 m/min
in the same condition. |
