Abstract
The temperature and temperature evaluation during shear cutting, particularly at increased
speeds, is crucial for understanding the material behavior during cutting, validating
thermo mechanical material models used in the finite element method, and predicting the tool wear.
In this study, we measured the punch force and temperature for EN AW 6082, zinc, and tin
for punch speeds 0.12, 0.2, 0.4, and 0.6 m/s using a cutting clearance of 0.075 mm. The
temperature is evaluated based on the thermoelectric voltages arising from the sheet metal
and tool material based on the Seebeck effect. The results demonstrate that the sheet metal
strongly influences the thermal response during shear cutting. Higher temperature maxima
were generally observed to occur later than the force maximum, likely due to additional
frictional heating beyond plastic deformation.
