Abstract
The effect of an electrospun (ES) film on the reduction of micro-drilling cutting force required for SUS304 plate was investigated. ES films were fabricated using the electrospinning method with polyvinyl alcohol (PVA) and polymethyl methacrylate (PMMA) as raw materials. The results of ATR-FTIR spectroscopy showed that there was no difference in the composition of the raw polymers and the fabricated ES films, and that the polymers were not altered. The diameters of the PVA and PMMA nanofibers were approximately 0.069–0.30 and 7.2 μm, respectively. The drill thrust force and run-out when using the nanofiber ES films were lower than those on an uncoated JIS SUS304 plate during the drilling. High-speed camera images showed that PMMA nanofibers pulverized by the cutting process adhered to the drilling tool surface and were guided into the drilling hole. This suggests that ES films made of organic polymer compounds, such as PMMA, are promising candidates for stable drilling, as they suppress drill run-out and act as an excellent lubricant during cutting.
