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.

A review on ductile mode cutting of brittle materials

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.
