Abstract. Shear cutting is one of the most important manufacturing processes due to its high productivity and process stability. The advantages of shear cutting also obtain in high-speed cutting and cutting with enhanced speed. In addition, further advantages such as high dimensional accuracy and a predominant fracture zone accompany it. At the same time, according to literature, high cutting speeds lead to increased temperatures in the shear zone, which can entail tool damage and wear in the short or long term. Knowledge of the temperatures is therefore indispensable for forward planning and economical production processes. Therefore, measurement of temperature in the shear zone has already been approached by a wide variety of methods. In this paper, the temperatures are determined by recording the thermoelectric voltages occurring during shear cutting with enhanced speed up to 270 mm/s and converting these voltages into temperature values using knowledge of the Seebeck coefficients of the punch and sheet material.
