Recently, composite materials were widely used in different applications due to their lightweight, and good thermal and mechanical properties.
In this study, an attempt to manufacture laminate composites by hand layup was performed.
Also, optimal parameters for the best surface roughness were investigated.
Therefore, three parameters had been examined; spindle speed, feed rate, and depth of cut.
The L9 Taguchi orthogonal array, signal to noise (S/N) ratio, and analysis of variance (ANOVA) were selected to determine the optimum parameters.
To create composites, the compression method was employed.
Four different types of composites were manufactured with 2.8 mm thickness, to determine the effect of the parameters on the surface roughness and for specified parameters using the CNC milling machine.
The weight fraction ratio of fibers was 39% , the polymer was 34% , and 27% for Aluminum.
The results showed that the optimum parameters for surface roughness in milling machine of composites for Polyester resin for aluminum–fiberglass composite are; spindle speed=5000 r.
