Successful of grinding in practice is highly depending on the level of expertise of the machinist and engineer. Knowledge Management might offer a strategy to keep the valuable knowledge. The main objective of Knowledge Management (KM) is to manage knowledge process, the knowledge itself could not be managed, what can be managed is the knowledge gathering, storing and organizing, retrieving, an...

To study the establishment of homochirality observed in the crystal growth experiment of chiral molecules from a solution under grinding, we extend the lattice gas model of crystal growth as follows. A lattice site can be occupied by a chiral molecule in R or S form, or can be empty. Molecules form homoclusters by nearest neighbor bonds. They change their chirality if they are isolated monomers...

The effect of ultraprecision grinding on microstructural change in silicon monocrystals, such as surface roughness and dislocation structure, was investigated both experimentally and theoretically. The study found that there exists an additional concentration of oxygen and carbon in an amorphous layer for all investigated grinding regimes with their distributions dependent on the grinding varia...

The following article examines the influence of glass-crystalline bond in grinding wheels with grains made from microcrystalline aluminum oxide, and specifically its effect upon the values of selected operational indicators in the process of traverse internal cylindrical grinding of surfaces made from Inconel® alloy 600. The experimental test results obtained showed that changes in the bond pha...

Grinding is one of the most widely employed manufacturing processes when accurate finishing of workpieces is required. In order to investigate the effect of processing parameters to grinding performance, soft computing methods constitute a reliable and economical alternative to other simulation methods, such as the Finite Element Method (FEM). In this study, a comparison between classical Artif...

This paper revisited some wheel–workpiece interaction problems in surface grinding including the profile of heat flux and the variation of the wheel’s elastic modulus. A method of using an optical microscope and a CCD camera was applied to capture the depth and width of the heated zone, the details of the temperature field and the stability of the heat flux. It was found that the heat flux in u...

A suitable grinding fineness and flow-sheet could potentially reduce the mechanical entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind size of this ore should be 92% passing 74 μm based on the mi...

Guidry, D. J. (Louisiana State University, New Orleans) and G. H. Trelles. Evaluation of a new method for the preparation of homogeneous mycelial suspensions. J. Bacteriol. 83:53-60. 1962.-An all-glass tissue homogenizer (providing both conical and cylindrical grinding surfaces) was employed in the preparation of homogeneous mycelial suspensions. Pellets of mycelium from constant shake liquid c...

Abstract: The specific rate of breakage is one of the most important factors in evaluation of grinding process especially in ball mill. In this article the effect of ball size and feed size on selection function were investigated using batch grinding circuit on two-iron ore anomaly (B, C) from sangan mine in north of Iran. Eight different monosize fractions were prepared between 2000 and 50...
