摘要:This study presents new information on single grit interaction behaviour and its brittle–ductile transition in micro-grinding single crystal silicon using a single grit diamond tool. A model to describe the energy interaction between the cutting behaviour of a single grit an...

摘要:Abstract(#br)The application of sapphire in micro-machining is often limited due to its high brittle feature. This study proposes and successfully fabricates a novel multi-layer toughening micro-structure (MTM) sapphire for improving its machinability in micro-grinding. A pr...
