Abstract
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.
