  • 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.

  • Ductile-Regime Grinding: A New Technology for Machining

    Because of recent advances in precision engineering that allow controlled grinding infeed rates as small as several nanometers per grinding wheel revolution, it is possible to grind brittle materials so that the predominant material-removal mechanism is plastic-flow and not fracture. This process is known as ductile-regime grinding.

  • Ductile or partial ductile mode machining of brittle materials

    grains are used for the fine grinding of brittle materials [22– 25]. These techniques result in the ductile mode fine grinding of brittle materials which produce a mirror surface finish (nanometre order surface roughness) and which do not require further finishing

  • A review on the current research trends in ductile regime

    Ductile regime machining is an alternative method for polishing of brittle materials to obtain a high quality surface finish by a ductile or plastic material removal process. Hence, there is a growing interest to study ductile regime machining over several decades.

  • Ductile or Partial Ductile Mode Machining of Brittle

    This paper reports ductile or partial ductile mode machining of silicon, glass and some advanced ceramics. Results are presented using scanning electron micrographs of the machined surfaces. Grinding and lapping operations using inexpensive machine tools could produce ductile streaks on surfaces of these brittle materials under good conditions.

  • Difference Between Ductile Material and Brittle Material

    Ductility or brittleness is highly temperature dependent. For example, a brittle material can behave like a ductile one at an elevated temperature. Similarly a ductile material at room temperature, when frozen, can automatically convert into brittle material. Ductility or brittleness of
