Taguchi Optimization

This project focuses on taguchi
optimization for tool wear in solid carbide end
mill. This project main of objectives Study the
general characteristics of tool wear and
Understanding the causes of tool wears and
their consequences and Set up the tool failure
criteria and understanding the meaning of toollife.
Tool wear optimization plays an important
role in industry for higher productivity and
product quality. Flank wear of cutting tools is
often selected as the tool life criterion as it
determines the diametric accuracy of
machining, its stability and reliability. In the
present work, tool wear is taken as the response
(output) variable measured during milling,
while cutting speed, feed, helical angle and
depth of cut, are taken as input parameters. The
L27 orthogonal array of a Taguchi experiment
is developed for four factors at three levels to
conduct experiments. Experiments have been
conducted for measuring tool wear based on the
orthogonal array of a Taguchi experiment in a
Vertical milling machine (HAAS Mill) on work
piece martial is SS304 and using a Solid Carbide
cutter. End mill tool wear was measured using
tool maker’s microscope. The measured results
were then collected and analysed with the help
of the commercial software package
MINITAB14. The experiments have been
conducted using Taguchi’s experimental design
