Abstract

Aerospace materials are hard to machine which can be done
by choosing the right tools and methods. There are plenty of
coated cutting tools currently used in aerospace industry such
as Titanium Aluminium Nitride (TiAIN), Zirconium Nitride
(ZrN), and many more. The application of coated tools has
become more important in machining process and mostly
been done by thermal spraying process such as Physical
Vapor Deposition (PVD). The major problems of these
processes are that they are costly due to high temperature
and complex procedures. Electroless nickel plating is nongalvanic
coating method that involves several simultaneous
reactions in aqueous solution, which occur without
consuming electrical power. By introducing this process, the
coating cost and procedure could be simplified. The method
used is by comparing tool wear of EN-CBN carbide tools
substrates with uncoated carbide tool. The design of
experiment is determines base on Taguchi L9 design of
experiment. This involves three parameters which are cutting
speed, feed rate, and depth of cut. Each of these parameters
consist of three level. During the project, equipment used are
Mitutoyo Surftest SJ-210 for measuring surfaces roughness,
while for flank wear, ZEISS microscope is used with ZEN
software. Lowest flank wear measure is 100.469 μm while the
highest is 401.341 μm. the surface roughness is not to
consistent, the lowest roughness is recorded 0.457 μm and
the highest is 1.275 μm. in the end of this analysis, the ENCBN
Carbide tool substrate generally able to slightly reduce
tool wear.
