Modeling and Simulation of Process-Machine Interaction

Interaction of process and machine in grinding of hard and brittle materials such as cemented carbide may cause dynamic instability of the machining process resulting in machining errors and a decrease in productivity. Commonly, the process and machine tools were dealt with separately, which does not take into consideration the mutual interaction between the two subsystems and thus cannot ...

Molecular Dynamics Simulation of Nano-Grinding with ...

During grinding a large number of micrometer or sub-micrometer grains remove material from the surface of a workpiece, acting as cutting tools. As the grains perform the material removal process, the alterations on the workpiece surface are correlated to the grain characteristics, as well as process parameters. In the case of nano-grinding, only several atomic layers are removed and surface ...

In Grinding, Coolant Application Matters

2008-3-1  I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the more coolant is applied. With conventional abrasive wheels, a flow rate of 2 gpm/hp is effective. For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well.
