        abstract = {Glass Fiber Reinforced Polymer (GFRP) composites are widely used in aerospace, automotive, marine, and structural applications due to their high strength-to-weight ratio, corrosion resistance, and excellent mechanical properties. However, drilling operations often cause defects such as delamination, fiber pull-out, and matrix cracking, which reduce component quality and performance. This study investigates delamination behavior during drilling of an 8-ply GFRP laminate using CAD/CAM simulation and Finite Element Analysis (FEA). A 2 mm thick laminate with [0/90/0/90] s fiber orientation was modeled and drilled using a 6 mm solid carbide twist drill. The effects of spindle speed (1000–3000 rpm) and feed rate (0.05–0.15 mm/rev) on thrust force, stress distribution, deformation, and delamination were analyzed using ANSYS Explicit Dynamics. Results indicate that higher feed rates increase thrust force and delamination, while suitable spindle speeds improve hole quality. The study identifies optimal drilling parameters for minimizing damage and enhancing machining performance in GFRP composites.},
