Abstract
The purpose of this article is to investigate the influence of the cutting parameters, such as cutting speed and feed rate, and point angle on delamination and surface roughness produced when drilling a glass fiber-reinforced plastic composite. All tests were run without coolant at cutting speeds of 5, 10, 15, 20, and 25 m/min and feed rates of 0.1, 0.2, 0.3, and 0.4 mm/rev and point angle of 118° and 135°. The damage generated associated with drilling GFRP composites was observed, both at the entrance and the exit during the drilling process. It was observed that the delamination on drilled holes increased with increasing cutting speed and feed rate. The best results of the delamination are obtained at lower cutting speed and feed rates. For minimum damage on drilled holes, glass fiber-reinforced plastic composite must be drilled at a lower feed rate. It is shown that the point angle of drill is an important parameter on delamination and surface roughness.Keywords
