Conditioning and monitoring of grinding wheels

intergranular space must be created within the dressing process. Metal bond grinding wheels are mostly used for superabrasive grains because of their improved bonding strength. From the appearance of the grinding wheel one can distinguish micro geometry and macro geometry. The macro geometry is described by a convex hull over all protruding grains in circumferential direction and average ...

Energy and temperature analysis in grinding

Well-designed grinding processes usually enhance workpiece surface quality producing low roughness, compressive or neutral residual stresses and improved fatigue life. Grinding is a very efficient process for machining hard materials and has the potential to achieve high accuracy of shape and size. Conversely, abusive machining can lead to a range of forms of surface damage. Generally, it is ...
