This paper researches and creates device for cutting temperature measuring when turning, using temperature sensors (thermocouple). Cutting temperature is measured at the zone closed the rake and center of contact of the chip-rake. Cutting temperature sensor is connected to the Amplifier and  collector, then temperature displayed on the screen of the temperature device or connected to collector, A/D card and processed by DASYLAB software (cutting temperature is displayed in graph or number). This device is used by the Industrial Machine Tools and Metal Machining Division (Mechanical Engineering Department - HAUI) for metal cutting experiments (in the metal machining course).
