Abstract

Nano/micro grinding of tungsten carbide (WC) mould inserts was performed. A form accuracy of ∼200 nm (in PV) and a surface roughness of ~7 nm were achieved. Nanoindentation revealed that small chipping or cracking occurred even at a penetration depth of 38 nm, which could hinder the further improvement of surface quality during grinding. It was found that when grinding was conducted at nanometric scale, the microstructure of the work material and the morphology of the WC grains should be taken into account to enable a fully ductile removal.
