This paper presents the surface roughness of aluminum silicon alloy (AlSi) matrix composite reinforced with aluminum nitride (AlN) using three types of carbide inserts. Experiments were conducted at various cutting speeds, feed rates, and depths of cut, according to the Taguchi method, using a standard orthogonal array L27 (34 ). Signal-to-noise (S/N) ratio and ANOVA were applied to study the characteristic performance of cutting speed, feed rate, depth of cut, and tool types in measuring surface roughness during milling. The surface roughness of the machined surface were observed using Mitutoyo Formtracer CS-500. Analytical results using the Taguchi method showed that enhanced surface roughness could be obtained using low feed rate, medium depth of cut, low cutting speed, and TiB2 insert. Optimal surface roughness was obtained under the following machining parameters: cutting speed, 230 m/min; feed rate, 0.4 mm/tooth; depth of cut, 0.5 mm, and TiB2 insert.
