| Abstract |
This work reports the influences of helix angle on
tool performances of titanium aluminum nitride (TiAlN)- and
diamond-like carbon (DLC)-coated carbide end mills for dry
side milling of 304L stainless steel. The study results revealed
that the number of axis contact points and effective cutting
length increased with increasing helix angle, leading to less tool
wear and thinner milled chips but higher workpiece temperature.
In addition, DLC-coated tools exhibited relatively high workpiece
temperature, rapid chipping wear due to thermally induced
graphitization, and chip-built-up on side edge while TiAlNcoated
end mills displayed less severe abrasive wear on cutting
and side edges. Moreover, the DLC-coated end mill with a high
helix angle of 60° gave the lowest surface roughness of 0.26 μm
within the cutting length of 20 m while the corresponding
TiAlN-coated tools offered longer tool cutting length of more
than 50 m with comparable surface finish. Consequently, the
TiAlN-coated end mill with a high helix angle of 60° offered
high-quality surface finish with long tool life time and would be
more useful for dry milling of stainless steels. |
