  • 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.

  • 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. This paper reviews current state of research and development in ductile regime machining.Ductile or Partial Ductile Mode Machining of Brittle Materials,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.

  • Recent developments in grinding of advanced materials

    for grinding of brittle materials was not available in the literature, and thus it was conducted by Sun et al. [13]. Parallel grinding with a much higher material-removal rate (MRR) in the ductile regime is found to be possible than cross grinding. Conventional grinding of BK7 glass usually leads to brittle fractured surfaces with severe subMaterials CORE,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.
