WebIt is evident that the surface roughness using castor, neem, and rice bran oils recorded a roughness value of less than 2 μm. It should be noted that the overall surface roughness requirement for finished bolt holes in turbine discs is given as Ra < 1.6 μm, and for pre-drilled holes, is Ra < 2 μm in drilling Inconel 718 [ 44 , 45 ]. WebMay 4, 2015 · If the tool life and surface roughness are considered, the better cutting condition is a cutting speed of 75 m/min, depth of cut of 0.6 mm and feed rate of 0.1 mm/r. In this case, the surface roughness is 0.59μm. dnd class overview
