Semi-Ductile Grinding and Polishing of Ophthalmic Aspherics and Spherics*

Deformation and material removal in a nanoscale multi-layer thin film solar panel using nanoscratch

“…Under such conditions, deformation was confined to the plastic zone, and material removal occurred in the ''ductile regime'', which prevented crack formation and surface damage [6][7][8][12][13][14][15]. With this understanding, ultra-precision grinding was successfully used to produce smooth surfaces of surface roughness in nanometer scale in materials such as glass, silicon, germanium, cemented carbides and other ceramics [11,[16][17][18][19][20]. However, little has been reported about its application in nanostructured multi-layer materials.…”

Gelling of chips during vertical surface diamond grinding of BK7 glass

“…It has been observed from work done in industry that large amounts of ductile streaks dramatically reduce polishing as seen from Fig. 1 [5].…”

Development of a novel binderless diamond grinding wheel for machining IC chips for failure analysis

“…Earlier success in partial ductile mode machining of optical glass and infra-red optics (Si and Ge) was encouraging [1]. Subsequent work in an optical industry revealed dramatic improvement in the grinding and polishing of optical moulds for making plastic lenses [2].…”
