Abstract: 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. The measurements have been performed at three different workpiece materials: carbon steel AISI 1045, aluminum alloy AA 7075, and titanium alloy Ti6Al4V. The influences of different parameters like cutting speed, feed, and position of the measurement spot on the temperatures have been investigated. The cutting speed has been increased from conventional values up to 100 m/s for AISI 1045, 117 m/s for AA 7075, and 10 m/s for Ti6Al4V. Additionally, a review of radiation thermometry techniques and applications regarding time resolved temperature measurements in metal cutting will be presented.
