Chip thickness ratio formula
http://www.minaprem.com/numerical/calculate-chip-velocity-from-cutting-speed-depth-of-cut-and-chip-thickness/ 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.
