• Material Removal - an overview ScienceDirect Topics

    W. Brian Rowe, in Principles of Modern Grinding Technology, 2009. Adaptive Dwell Control. Material removal lags behind programmed values owing to deflections of the system. A measure of the lag is given by the time constant of the grinding system. This means that accuracy achieved depends on the dwell employed for spark-out.

    This means that the trajectory of some beads cross over from compartment C5 to C4 during the ascending motion and vice versa on their way down. Through this first example of the axial grinding media distribution several transport phenomena could be revealed giving an idea of the IsaMill™ performance.
