概要: Tool face temperature of single crystal diamond in high precision orthogonal cutting of aluminum and copper is measured using two-color pyrometer with an optical fiber. The infrared rays radiated from the chip-tool interface and transmitted through the diamond tool are accepted by an optical fiber and led to two-color detectors of different spectral sensitivity. Temperature distribution on the tool face is analyzed by employing finite element method and calculated results are applied to the estimation of the maximum temperature on the tool face. The results obtained are as follows; (1) The technique developed is suitable for measuring the tool face temperature in single crystal diamond cutting. (2) Output wave of temperature was clearly recorded. The tool face temperature measured is approximately 190°C for Al and approximately 220°C for Cu when cutting speed was about 620m/min. (3) The temperature increases with the increase of cutting speed. (4) The temperature on the tool face measured is in good agreement with that calculated. 続きを見る
