Every machining operation leaves characteristic evidence on the machined surface. Each type of cutting tool leaves its own individual pattern, which can be identified as surface roughness. This research aims to enhance the surface finish quality by investigating a new method depending on the pattern left by the cutting tool. Formulae for the new method (two pass) were presented and discussed. Practically, the new technique improves surface roughness, straightness error, and roundness error by more than 50%, 51%, and 42%, respectively, at the proposed cutting condition for all used workpiece materials.
