The aim of this work is to analyze the micro mechanisms underlying the wear of macroscale tools during diamond machining of SiCp/Al6063 composites and to develop the mechanism-based diamond wear model in relation to the dominant wear behaviors. During drilling, high volume fraction SiCp/Al6063 composites containing Cu, the dominant wear mechanisms of diamond tool involve thermodynamically activ...

This work studies the open hole surface integrity of Al 2024-T3/Ti-6Al-4V stacks, which have been subjected to different making methods, namely, conventional drilling and helical milling. The resulting hole-exit burr, roughness machined surface/sub-surface microstructures characterized impact on fatigue performance coupons has revealed. Results show that milling can effectively reduce burr form...

Residual stresses are balanced, non-uniform, undesirable, and often harmful in laminated polymer composite materials. Different methods developed to measure these composites. In this manuscript, three experimental measurement methods, namely ‘hole drilling’, ‘slitting’, ‘curvature’ considered, the results compared with those of classical lamination theory (CLT). It is demonstrated that hole dri...
