Effect of feed rate on tool wear and surface condition during milling of CFRP
Application of carbon fibre reinforced polymers (CFRP) is rapidly increasing for use in industrial applications such as in the aerospace and automotive industry. However, issues such as rapid tool wear during CFRP milling remain significant, due to the abrasiveness of the carbon fibre. Thu...

Summary: | Application of carbon fibre reinforced polymers (CFRP) is
rapidly increasing for use in industrial applications such
as in the aerospace and automotive industry. However,
issues such as rapid tool wear during CFRP milling remain
significant, due to the abrasiveness of the carbon fibre.
Thus, this study was conducted to investigate the effect of
feed rate (1250, 1500 and 2500 mm/min) on tool wear
and surface conditions during milling operations. The
cutting speed and depth of cut were kept constant during
the milling test at 100m/min and 3 mm respectively.
Milling of CFRP with an uncoated tungsten carbide end
mill was carried out and the progression of tool wear was
observed until a machining length of 6000 mm. It was
observed that the lowest tool wear was achieved when
employing the highest feed rate of 2500 mm/min. It was
observed that all cutting tools experienced abrasive wear
as it was observed that pull out of WC-Co occurred on the
flank surface of the cutting tool. The abrasiveness of CFRP
leads to the flank wear of the carbide cutting tool.
Damages such as fibre pull out, delamination and matrix
smearing were observed on the CFRP machined surface. |
