Ductile-Regime Grinding: A New Technology for Machining,
01-05-1991· This process is known as ductile-regime grinding. When brittle materials are ground through a process of plastic deformation, surface finishes similar to those achieved in polishing or lapping are produced. Unlike polishing or lapping, however, grinding is a deterministic process, permitting finely controlled contour accuracy and complex shapes.
Science and art of ductile grinding of brittle solids,
01-02-2021· In brittle solids with dominant covalent–ionic bonding—single crystals, glasses, polycrystalline ceramics—grinding in the ductile regime has received special attention as a means of producing smooth surfaces with minimal residual damage [ [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15] ].

A review on ductile mode cutting of brittle materials,
14-02-2018· But obtaining smooth and damage-free surface on brittle materials by traditional machining methods like grinding, lapping and polishing is very costly and extremely time consuming. Ductile mode cutting is a very promising way to achieve high quality and crack-free surfaces of brittle materials.
