摘要：
Drilling of composites are generally associated with fiber pull out and delamination. The aim of this paper is to optimize the drilling process parameters and study the influence of twist drill bit geometry like point angle on delamination by FE analysis and experimental studies. Using DOE technique, different speeds and feed rates are used to carry out drilling of CFRP laminates experimentally and by ABAQUS. Delamination area of CFRP drilled hole from simulation and experimental results are analysed using Image J software. Speed of 3500 rpm and a feed rate of 0.1 mm/rev is found to be optimum value. Further, point angle in drill bit geometry is modified to 90(0), 118(0) and 135(0) and effect of delamination is simulated and studied using ABAQUS. (C) 2019 Elsevier Ltd. All rights reserved.
