  • 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.

    uctile regime grinding brittle materials This process is known asductile-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.

  • Ductile-Regime Grinding of Brittle Materials NIST

    Ductile-Regime Grinding of Brittle Materials. Published. January 1, 1997. Author(s) Kenneth Blaedel, John S. Taylor, Christopher J. Evans. Abstract Under appropriate conditions, brittle materials may be ground to produce surfaces with no observable fracture damage. This chapter reviews the techniques for producing such surfaces and the mechanisms of material removal involved. Citation. Chapter

  • Ductile Regime Grinding Brittle Materials

    Dec 16, 2014 Ductile regime grinding is an effective machining process that has been used for brittle materials for several years now. In ductile regime grinding, material is removed through plastic deformation, which reduces the risk of fractures and compromised materials.

  • Ductile-regime machining model for ultrasonic elliptical

    01/12/2018· Ultrasonic elliptical vibration cutting (UEVC) is attracting much attention in ultra-precision machining of brittle materials as it was found be able to effectively increase the critical depth of cut (d c) of brittle materials.However, the mechanisms for the increased d c are still not fully understood. In this study, a ductile-regime machining model was developed for the UEVC of brittle

  • A review on the current research trends in ductile regime

    09/02/2012· 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.

  • 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.

  • Ductile or partial ductile mode machining of brittle materials

    Conventional grinding of brittle materials normally produces 100% fractured surfaces requiring lapping and polishing. However, the concept of duc- tile mode machining has led to many innovative applications for machining brittle materials, such as glass, Si, Ge and SiC [7–11].
