• Ductile-Regime Grinding: A New Technology for Machining

    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.

    Ductile-Regime Grinding Of Brittle Materials: Experimental

    Ductile-regime grinding is a new technology made possible by the use of real-time control and precision engineering in the grinding process. By ensuring that the abrasive grinding forces do not exceed a threshold value, it is possible to grind materials that are normally considered "brittle" in such a way that the material removal takes place through plastic deformation rather than fracture.

    In order to improve the surface integrity of these materials, ductile mode cutting (DMC), also called ductile regime cutting or ductile cutting, as a promising technique, has been studied vigorously over the past decades and it is commonly understood that DMC is to remove work materials by plastic flow instead of brittle fracture deriving a damage-free surface.
