Micro-end-milling of carbon nanotube reinforced epoxy nanocomposites manufactured using three roll mill technique

Carbon nanotubes (CNTs) have been applied as nano-fillers to improve mechanical, thermal and electrical properties of polymers. Despite near net shape techniques could be used manufacture nanocomposites, micromachining processes are still necessary attain high surface quality dimensional accuracy. Besides, nanocomposites a potential approach produce micro-features/components, following the miniaturisation trend modern manufacturing. Therefore, micro-machining these relatively new materials needs investigated. A comprehensive investigation on machinability will presented in terms chip formation, cutting force, tool wear, morphology roughness. Three controlled quantitative factors investigated at different levels, including filler loading, speed feed per tooth (FPT). Micro-slotting is performed an ultra-precision desktop micro-machine using uncoated carbide micro-end mill. The additions multi-walled carbon nanotube (MWCNT) shown significant effects epoxy-based dramatic reduction force machined roughness with accelerating wear compared neat polymer. irregular variations when micro-milling epoxy/MWCNT rates below minimum uncut thickness (MUCT) (lower than 2 ?m) indicating by their fluctuations that from those higher rates. It possibly shows impact size illustrated observations morphology, profiles well specific energy calculation.
