Prediction of Tool Lifetime and Surface Roughness for Nickel-Based Waspaloy

Table 4

Linear formula of tool wear on surface roughness, where SR is the surface roughness (Ra, μm) and VB is the tool wear (mm).

Cutting parameters	Linear formula
V = 40 m/min, fz = 0.3 mm/tooth, ap = 0.3 mm
V = 37.5 m/min, fz = 0.35 mm/tooth, ap = 0.25 mm
V = 35 m/min, fz = 0.4 mm/tooth, ap = 0.2 mm
