Abstract The engine block, also known as cylinder block, is the primary automotive
component for any automobile. A cylinder block is the housing where all engine components
reside. One of the most specific customer criteria for machine components is surface finish.
Surface roughness is an essential indicator of surface finish on machined items. Thus, the
researcher underwent the experiment to determine the surface roughness result of the aluminum
engine block by using the milling machine. Using Taguchi Method, the effects of different
milling process parameters such as cutting speed, depth of cut, and feed rate on surface finish
were examined. To achieve the minimum surface roughness and the optimum values obtained
for cutting speed and depth of cut were, respectively, 750 RPM, 850 RPM, 950 RPM, and
0.3mm, 0.6mm, and 0.7mm. Meanwhile, the feed rate value is constantly 0.4mm/min for all
the experiments. According to the Taguchi design analysis observations, the cutting speed has
the most significant influence on the modeling surface roughness. The S-N Ratio graph depicts
the ideal setting of the machining parameter that results in the best surface roughness. The
analysis of the results specifies that the optimal cutting parameters combination for a good
surface finish is high cutting speed and low depth of cut.
