Abstracts : In today’s competitive and dynamic market
environment, the main confront of metal-based
industry is to maintain higher productivity and the
surface excellence of the machined parts. In utmost
situation, performance of turning process is
measured in terms of quality of surface generated.
Fatigue strength, corrosion resistance and creep life
increases as superiority of turned surface improves
significantly. Therefore ideal surface finish is usually
required and appropriate parameters need to be
selected to achieve required quality of surface. The
present research intends to apply use of Taguchi
method to carry out performance analysis of the CNC
turned parts to achieve high surface finish on copper
alloy material. This paper explores the corollary of
process parameters in turning of copper alloy on
HAAS CNC lathe machine. In this research work,
Taguchis L9 orthogonal array is used to carry out
CNC turning operation on copper alloy. To study the
performance characteristics in CNC turning signal to
noise ratio is evaluated. The output response like
surface roughness is analyzed considering effects of
factors like spindle speed, tool feed rate and uncut
depth of work piece or depth of cut for tool. For
predicting the surface roughness, regression
mathematical model (in terms of linear and
quadratic terms) has also developed from the
experimental result, which will be useful to envisage
surface roughness value on different combination of
selected parameters. From verification experiments
it is observed that, calculated surface roughness
from model equation varies in the range of 0 to 10%
with respect to an experimental value. Thus, it is
possible to obtain effective machine utilization and
present work will be quite useful for manufacturing
engineers working in the field of CNC Machining.
