2016 8 19 Cross grinding and parallel grinding are two typical grinding modes. A significant comparison of these modes for grinding of brittle materials was not available in the literature and thus it was conducted by Sun et al. 13 . Parallel grinding with a much higher material removal rate MRR in the ductile regime is found to be possible than

2012 5 31 Figure 1. Schematic diagram of a grinding passage. Before the grinding process is started grains must undergo the cleansing process. This is followed by a conditioning process that ensures a uniform moisture content for the entire lot of grains helping endosperm softening and cover harshening which improves the separation process.
