Micro Self-Sharpening of Cutting Edges in cBN Grinding

Fractal Analysis of Micro Self-Sharpening Phenomenon in Grinding with Cubic Boron Nitride (cBN) Wheels

New Diamond Grinding Wheels with Electrically Conductive Cutting Edges

The application of an electrically conductive diamond material to a new type of grinding wheel whose cutting edges possess electrical conductivity has been tried in this research work. Firstly, electrical discharge machining is applied on a solid surface of an electrically conductive CVD diamond film to create protrusions like cutting edges. Secondly, it is confirmed that the EDMed surface of t...

Micro Cutting Simulation of Abrasive Grains in the Grinding Process

In the current work we present approach to study the mechanism of the cutting of abrasive grains in the grinding wheel using finite element analysis (FEA). The simulation process is done by separating two abrasive grains from the grinding wheels and the microprocess of material removal in the case of surface grinding is simulated. Modelling was done on the workpiece steel S-7 and material grain...

Modeling and Analysis of Contact Conditions during NC-Form Grinding of Cutting Edges

Due to increasing demands on cutting tools, cutting edge preparation is of high priority because of its influence on the tool life. Current cutting edge preparation processes are mostly limited to generating simple roundings on the cutting edge. Multi-axis high precision form grinding processes offer great potential to generate defined cutting edge microgeometries. Knowledge about the relation ...

Molecular Informatics: Sharpening Drug Design’s Cutting Edge

The word ‘drug’, which derives from the Middle English word ‘drogge’, first appears in the English language during the 14th century and it has, at least during the last century, become, arguably, one of the most used, and misused, of words, becoming tainted by connotations of misuse and abuse. The dictionary definition of a drug is: ‘a substance used medicinally or in the preparation of a medic...
