WebA moderate removal rate of Q = 50 mm 3 /s over a 25-mm wide cut is quoted as Q′ = 2 mm 3 /s per mm width or 2 mm 2 /s equivalent to 0.186 in. 2 /min in British units. 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). WebChip thickness calculations for round and radius insert cutters. The chip thickness, h ex, ... Feed can be increased by the modification value in the table below depending on the ratio, a e /DC. Example: DC 20 mm – a e = 2 mm, a e /DC = 10% h ex = 0.1 mm, f z = 0.17 mm/tooth. Width of cut diameter ratio, a e /DC: Modification factor: f z (mm ...

WebSince lower surface roughness indicates better surface quality, we measured the surface roughness and utilized the smaller-is-better formula (i.e., Equation (7)) to calculate the S/N ratios. Table 14 shows the results for the measured surface roughness, along with the mean values, and the calculated S/N ratios from the experiments.
