Effect of Grit Spacing on Hole Diameter Accuracy and Roughness of CFRP Laminate Drilled with Brazed Diamond Corn Drill
Hole diameter accuracy end roughness are focused in the drilling of carbon fiber reinforced plastics (CFRP) laminate with brazed diamond core drill without coolant.The effect of grit spacing on hole diameter accuracy and roughness in drilling CFRP at different feed speed is studied.A simulation of heat conduction of CFRP laminate is performed to calculate thermal deformation of bole diameter.The study results indicate that bole-enlargement factor decreases with the increase of grit spacing and feed speed,and grit spacing has a relatively larger influence on enlargement factor.The surface roughness of hole wall increases with the increase of grit spacing and feed speed.When grit spacing of brazed diamond core drill is 1.6 mm and feed speed is 150 mm/min,hole quality of CFRP laminate is perfect.
