Abstract

This study aimed to estimate the axial stress and torque on a shaft in a disc cutter. The corresponding inner temperature and the surface temperature of a cutter ring were also measured by using strain gauges and thermocouples during the linear cutting tests. The maximum values of the axial stress and torque were recorded to 11.3 MPa, 171 kN․ m respectively. They have higher correlations with normal force rather than rolling force. The results of temperature measured by thermocouples during a linear cutting test showed that the rate of increase in temperature was below 0.2℃. When the cutter spacing is set to be 70 mm, the inner temperature and surface temperature of a disc cutter were 0.1℃/m, 0.15~0.17℃/m respectively. Similarly, when the cutter spacing is 90 mm, the temperature values were 0.09℃/m, 0.13~0.23℃/m respectively.
