Mar 29, 2006· From this basis equation 4 can be used to predict the maximum feedrate (f max) for a given tool such that microfracture damage does not propagate below the cut surface plane. (4) where d c is the critical chip thickness, y c is the depth of surface damage and R is the tool radius. Another important finding from this work was that the nominal depth of cut (d), as shown in Figure 2, has little ...

AbstractThis paper reports the ultraprecision grinding of tungsten carbide for spherical mirrors with nanometre surface roughness and submicron form accuracy. Spherical grinding was conducted with a computer numerical control grinding machine using a metalbond diamond tool with grit size of 15 μm. Form accuracy and surface roughness were investigated as functions of the grinding conditions.
