Material Removal Rate - an overview ScienceDirect Topics

In HEDG, a possible removal rate as high as Q = 1200 mm 3 /s over a grinding width of 2 mm translates to Q′ = 600 mm 2 /s (or 55.8 in. 2 /min). Such high removal rates create high stresses on the grinding wheel grains and require appropriate grinding wheel design to avoid rapid wear. The HEDG operation removes material 300 times faster.
