Abstract
The demand for high strength and low weight material in aerospace industries is found to be
increasing in fabrication of structures and equipment’s of aircraft and space satellites.
Aluminium alloys possesses the characteristics of lightweight and high strength. The
identification of the optimum values of input parameters to achieve better surface finish as
response parameters is the prime objective of the project. The Aluminium 7075 T651 is worked
on the End milling process on the HAAS CNC machine. Different parameters of Cutting Speed,
Feed, and Depth of Cut in the Orthogonal Array method using Taguchi method. The results are
to be worked on the DOE method on software MINITAB.
The material can further be worked upon different input parameters on various machines and for
different response parameters. For carrying out the above-mentioned process various papers were
referred for guidance and knowledge in the same field of previously carried experiments and
results. Various technical concepts and tools like The Taguchi, Orthogonal Array, DOE,
ANNOVA, Fuzzy Logic, and Response Parameters etc. were learned from the Published papers
and it helped extensively in gaining knowledge required for the experiments to be performed on
our project.
