Abstract:
Metal matrix composites (MMCs) have emerged as a significant leading material in composite
materials in recent trends in research as well as in several application sectors, and particle reinforced aluminum MMCs have drawn significant interest due to their superior engineering
features. In this study, the effect of process parameters (speed, feed rate, depth of cut) on
turning of Sic particulate reinforced aluminum matrix composite was investigated.27 samples
(3 types,9 specimens in each were prepared by varying weight percentages (4%,8%,12%) of
sic using stir casting technique. The machining test was performed on a CNC lathe machine
using the provided machining parameters of speed, feed rate, depth of cut, and their selected
levels. The effect of the process parameters on Surface roughness and material removal rate
was investigated. A model was developed utilizing DOE in Minitab 18.1 to analyze the effect
of the process parameters on the machining performance measures. The major objective of
this investigation is to perform the experiments by considering various variables and their
levels, using TAGUCHI and ANOVA, and then assessing the findings. Based on the obtained
results surface roughness was greatly affected by feed rate followed by the depth of cut and
speed and lower surface roughness was optimized in the 10th run at a feed rate of 0.15rev/min,
depth of cut at 0.5mm, and speed at 500 rpm. While material removal rates were greatly
affected by speed followed by the depth of cut and feed rate and the greater material removal
rate was optimized in the 27th run and speed at 700 rpm, depth at 1.0mm, and feed at 0.25
rev/min.
