Effect of erodent hardness on erosion of brittle materials
Wear, 1988Abstract Data in the literature suggest that the relative hardness values of the erodent particles and the target sample may play a significant role in the erosion behavior of ceramics. This effect was investigated systematically. When the ratio of the target hardness to the hardness of the erodent particle approaches unity, there is a sharp ...

Use of ELID-grinding on brittle-hard materials
International Journal of Mechatronics and Manufacturing Systems, 2011Electrolytic in-process dressing (ELID) is a grinding technology which enables to manufacture surfaces in a quality that is close to polished on advanced, brittle-hard materials such as used in optics. ELID grinding requires exactly aligned machining parameters of the grinding process.

Removal Mechanism in Wire-Sawing of Hard-Brittle Material
Materials Science Forum, 2004A better understanding of the hard-brittle material removal mechanism in wire-sawing provides a basis for optimizing the wire-saw and processing parameters. The maximum cutting depth of each diamond grain in wire-sawing is given. It is proved theoretically that the deformation mode on the machined hard-brittle material surface gradually shifts from ...

Versatile facility for shaping hard and brittle materials
Review of Scientific Instruments, 1982A simple-to-construct attachment for a conventional wafering machine is described. The attachment incorporates an ultra-high-speed air turbine with a diamond needle cutting tool, and turns the wafering machine into a versatile milling machine for hard and brittle materials.

Fixed Abrasive Lapping and Polishing of Hard Brittle Materials
Key Engineering Materials, 2010Fixed abrasive lapping and polishing (FALP) is a new machining technology and was adopted to manufacture hard brittle materials and obtain the high productivity because of fixed abrasive. The preparation process of fixed abrasive pad (FAP) was described. FALP of K9 glass, mobile panel glass and Si were investigated with fixed 5-10 µm diamond abrasives.

Theoretical model of hardness anisotropy in brittle materials
Journal of Applied Physics, 2012Anisotropy is prominent in the hardness test of single crystals. However, the anisotropic nature is not demonstrated quantitatively in previous hardness model. In this work, it is found that the electron transition energy per unit volume in the glide region and the orientation of glide region play critical roles in determining hardness value and ...

Ductile to brittle transition in ultra-micro-grinding (UMG) of hard brittle crystal material
The International Journal of Advanced Manufacturing Technology, 2018In this study, ductile to brittle transition in ultra-micro-grinding (UMG) of hard brittle material is investigated. The characteristics of UMG process are studied, and differences between UMG and micro-grinding (MG) are investigated. The grain penetration depth considering rotary deviation is calculated, grain invalid cutting phenomenon is discussed ...
