In the present work, an attempt has been made to model the machinability evaluation through the
response surface methodology in machining LM25 Al/SiCp MMC manufactured through stir cast
route. The influence of four machining parameters including spindle speed (N), feed rate (f),
depth of cut (d), and various percentage weight of silicon carbide (S) on surface roughness (Ra)
was studied. The concept of Design of Experiments (DOE) was used for necessary
experimentation. The experimental results were analyzed statistically to study the influence of
process parameters on surface roughness.
