Chip Separation

A coupled thermoelastic-plastic plane-strain finite element model is developed to study orthogonal cutting process with and without flank wear. The cutting process is simulated from the initial to the steady-state of cutting force and cutting temperature, by incrementally advancing the cutting tool forward. Automatic continuous remeshing is employed to achieve chip separation at the tool tip regime. The effect of the degree of the flank wear on the cutting forces and temperature fields is analyzed. With the flank wear increasing, the maximum cutting temperature values on the workpiece and cutting tool increase rapidly and the distribution of temperature changes greatly. The increase of tool flank wear produced slight increase in cutting forces but significant increase in thrust forces.

This paper details experimental results when turning Ti-6Al-4V using water-miscible vegetable oil-based cutting fluid. The effects of coolant concentration and working conditions on tool flank wear and tool life were evaluated. L27 fractional factorial Taguchi array was employed. Tool wear (VBB) ranged between 28.8 and 110 µm. The study concluded that a combination of VOs based cutting fluid concentration (10%), low cutting speed (58 m/min), feed rate (0.1mm/rev) and depth of cut (0.75mm) is necessary to minimise VBB. Additionally, it is noted that tool wear was significantly affected by cutting speeds. ANOVA results showed that the cutting fluid concentration is statistically insignificant on tool flank wear. A notable increase in tool life (TL) was recorded when a lower cutting speed was used.

This study was conducted to investigate the effects of tool edge geometry on cutting temperature in the continuous cutting of case hardened steel. The tool edge temperature was measured using a two-color pyrometer with an optical fiber. The tool flank temperature increased with the negative land angle. When the flank wear VB was 0.05 mm, the tool flank temperature was only a little higher than with a new insert. However, when the flank wear VB was 0.1 mm, the tool flank temperature was dramatically higher. A horned insert resulted in higher tool flank temperature than when an insert without a horned edge was used. The tendency was remarkable at larger negative land angles and wider flank wear widths. Tool flank temperature increased with an increase in the nose radius of inserts. When comparing inserts with the same nose radius, the insert with the wiper edge caused higher tool flank temperatures than did the insert without the wiper edge.
