moreThis paper aim is to review the study of the effect of drilling parameter such as cutting velocities, feed rates and drill diameter and peel up and peel down mechanism at entrance and exit side. The orientation angle of fibre is in the form of 0, 45,-45, 60,-60, 75,-75, 90,-90 degree. The quality of drilled holes on hole wall delamination of polyurethane foam sandwich structure clarify the interaction mechanism between fibre, foam and drilling tool. Different damage has been conceptualized and methodologies provided to avoid damage in drilling of sandwich structure. Drilling tests were carried out on sandwich structure with conventional HSS drill bit. It is observed that experimental parameters were selected as per design of experiment. 27 experiments were performed varying the drilling parameters and measured the thrust force and torque. Cutting velocity is the factor influence the delaminating factor (Fd) followed by speed (450,852 and 1860 rpm) feed rate (0.104, 0.211 and 0.315mm/rev) and drill diameter (3, 4 and 5mm). Interaction factors are drilling velocity/feed rate, drilling velocity/speed and drilling velocity/drill diameter found out. Error associated with ANOVA FEA analysis. Compared with experimental ANOVA to FEA analysis.
