The primary objective of this work is to compare the effect of tool material during trepanning of woven CFRP composites. Composites are commonly used, especially, for their lightweight, stiffness, and strength. Trepanning is a machining operation especially performed for creating an effective hole in CFRP composites. The experiment is performed with two trepanning tools [polycrystalline diamond (PCD) and solid carbide tool (SC)] at different feed and spindle speed. The measured parameters such as thrust force and torque of the tool are measured using dynamometer, and the acoustic emission signal is obtained using AE sensor for analysis. The acoustic emission (AE) indicates the crack propagation occurred during trepanning of CFRP composites. The voltage obtained is high when the shearing of last ply occurs (post-delamination occurs). It is found that the PCD tool material has higher magnitude of thrust force compared to carbide tool material. The delamination factor obtained indicates that the increasing feed increases the delamination factor. The delamination factor is less with the usage of PCD tool at low feed compared to the solid carbide tool. It is found that, the delamination factor can be controlled by using suitable tool material and machining parameters such as spindle speed and feed. Thus, the amount of delamination is found to be small with PCD tool compared to the solid carbide and less feed and high spindle speed is recommended for good dimensional accuracy of hole.
