Abstract

Fabrication of high-quality optical lenses and reflectors demands the ultraprecision cutting of materials using micron to submicron uncut chip thicknesses (ac). At this scale, surface topography is significantly influenced by the interaction between the cutting tool and grain orientation/boundary effects. In this study, micro-scratching tests on coarse-grained, oxygen-free, high-conductance (OFHC) copper were performed with an increasing depth of cut, and the topography of the surfaces was characterized. The results were in agreement with previous work performed by other researchers. Acoustic emission (AE) was used to monitor the cutting process..
