metadata.conference.dc.description.abstract: Drilling is the most frequently employed operation of secondary machining for composite materials owing to the need for structure joining. However, drilling composite materials present number of problems such as delamination. Delamination has been a major form of failure in drilled composite materials due to the composites lack of strength in the drilling direction, which results in poor surface finish, reduction in bearing strength, reduction in structural integrity and ultimately poor performance of the composite. This present paper investigated the effects of drilling parameter by drilling the holes on the coconut meat husks reinforced polyester composites and evaluate its hole quality by measuring delamination. Drilling process is carried out for three spindle speed (1500 rpm, 2000 rpm and 2500 rpm) and three feed rate (0.1 mm/rev, 0.2 mm/rev and 0.3 mm/rev) by using a carbide twist drill. The results indicate that by using lower feed rate, it can obtain minimum delamination while effect of increasing spindle speed showed less influenced.
