Chip formation mechanism during orthogonal cutting of rubber microparticles and silica nanoparticles modified epoxy polymers

Abstract The addition of well-dispersed nanoparticles can significantly increase the mechanical properties and toughness epoxy polymers. In this study, an resin was modified by silica nanoparticles, (CTBN) rubber microparticles a combination both. An in-situ orthogonal cutting rig combined with high magnification high-speed imaging system used to determine effects on chip formation mechanism machining induced damage material. This study indicates that in silica-modified is governed fracture process large cracks both at machined surface level subsurface within zone. presence enables larger plastic deformation epoxy-modified polymer as toughening deflects generated primary magnitude found be lower for correlated observed during cutting. higher linked material’s poor resistance crack initiation growth. These findings effect will give engineers greater ability create trade-off between filler vs material Design Manufacturing (DFM) stages product design.
