Tool condition monitoring of aluminum oxide grinding …

The grinding operation gives workpieces their final finish, minimizing surface roughness through the interaction between the abrasive grains of a tool (grinding wheel) and the workpiece. However, excessive grinding wheel wear due to friction renders the tool unsuitable for further use, thus requiring the dressing operation to remove and/or sharpen the cutting edges of the worn grains to ...

Metallographic Polishing and Grinding

Rough grinding produces a flat, plane surface and removes harmful effects resulting from cutting-off operations. It is advisable during the rough grinding operation to bevel the sharp edges of the specimen, or specimen mount to prevent tearing of grinding papers and polishing cloths during subsequent operations.
