Özet
Glass fber-reinforced plastic (GFRP) composites take place in engineering materials owing to their low-weight and
high-mechanical properties. In some cases, they need to be shaped by machining before using in industrial applications. However, when these composites are machined, many problems such as bad surface quality, rapid tool wear are
encountered. Therefore, optimization of cutting parameters is essential to eliminate or minimize these problems. In this
study, GFRP composites were produced by combining polyester matrix material with glass fbers (GF) having 6 mm,
6–12 mm, 12 mm fber length, and 20%, 25%, 30% fber ratio by weight. The tensile strengths of these composites were
investigated. Turning tests were also performed with cutting speeds of 40, 80, and 120 m/min, feed rates of 0.1, 0.2 and
0.3 mm/rev, and depth of cut of 1, 2, and 3 mm, according to Taguchi L27 standard orthogonal array method. The efect
of fber length and ratio, and cutting parameters on cutting forces and surface roughness were analyzed. As a result of
the experiments, it was observed that the reinforced polymer matrix with GF provide to increase the tensile strength.
The highest tensile strength was obtained as 55.95 MPa from the composite having a fber length of 12 mm and a fber
ratio of 25%. Besides, the feed rate was determined as the most efective parameter among the all parameters on both
cutting force and surface roughness. Therefore, the feed rate should be chosen low for lower cutting force and surface
roughness values.
