...Masahiko Sato; Naoki Tamura; Hisataka Tanaka This paper describes the cyclic temperature variation beneath the rake face of a cutting tool in end milling. A newly developed infrared radiation pyrometer equipped with two optical fibers is used to measure the temperature. A small hole is drilled...

... using a two-color pyrometer. The tool temperature in dry cutting at a cutting speed of 300 m/min is ∼ 1060 ° C , but it is ∼ 1000 ° C when oil mist is supplied. In intermittent turning, the oil mist has more effect on the tool temperature because it is supplied more efficiently to the tool-chip...

...Bernhard Mu¨ller; Ulrich Renz; Stefan Hoppe; Fritz Klocke A fiber-optic two-color pyrometer with high spatial and temporal resolution has been applied to measure temperatures at an external turning process. Different measurement positions have been realized at the chip and the workpiece...
