Two-way ANOVA is used to analyze the data. The
results found that (a) both spindle speed and feed rate are significant over the process variations on the perimeter of
a component; (b) feed rate is more significant on the outcome when compared to spindle speed; (c) process
variations found on the perimeter of the component size 2 mm thickness are more when compared to a component
size 4 mm thickness; and (d) mathematical models are derived for determination of optimum cutting parameters to
achieve tighter process variations.
