“…Because the workpiece and toolholder are deformed, the relative position of the workpiece and the tool changes, resulting in vibration, causing machining errors and reducing the surface quality of the workpiece. The mathematical equation describing the vibration phenomenon of the turning process presented by M. Siddhpura and S. Katiyar as follows [4,5]: (1) where: m, k and c are the mass, stiffness and damping coefficient, respectively, and P(t) is the cutting force in feed (x) direction. P(t) = (2) where: Kf is the cutting coefficient in feed direction, b is the chip width (width of cut), T is the time delay between current time and previous time, and is the dynamic chip thickness due to the tool vibration.…”

Currently, there are advanced metal cutting processing methods such as electric discharge cutting, wire cutting, water jet cutting, but the metal cutting processing method is still very popular in the industry with its own advantages. The turning machining method is the same, in addition to the advantages, this method also has disadvantages. One of the disadvantages not achieving roughness as high as that of the finishing methods is the surface quality of the workpiece. One of the causes is the vibration of the workpiece and the tool during the machining process. This paper focuses on simulating the tool stiffness to the surface quality of the workpiece. The study has determined that the effect of the tool stiffness on the surface roughness is as a nonlinear function.
