Analysis:
Upon inspecting the cutting edges of both end
mills under microscope there is little wear on
the end mill used to machine DC53 while there is
extreme wear on the end mill used to machine D2,
in spite of the machining and clamping
conditions being identical. Thus, DC53 because
of the perfectly spheroidized primary carbides
in its structure has better machinability.

Analysis:
Upon inspecting the Drill point edges of both
drills under microscope little wear on cutting
edge is evident on the drill used to machine
DC53 while there is significant wear on the
cutting edge on the drill used to machine D2,
thus further emphasizing that DC53 has better
machiniablity than D2.
Conclusive
Result:
DC53 is superior to D2 in machinability.
Therefore, the use of DC53 is expected to
provide relatively longer tool life and reduces
the machining time in various applications.
With DC53 you
should experience a minimum of a 20-30%
reduction in machining time, when compared to
D2. Individual results can vary depending on the
power, rigidity, and spindle speed of the
machine being used. Rigidity of set up can also
be a factor. But as a rule of thumb, start by
increasing surface speed by 20% over what you
use for D-2. When you are satisfied with surface
speed, increase feed rates by 10% increments or
depth of cut by 10% increments. You will find
the combination that best suits you equipment
and conditions.
