Abstract：Cutting temperature distributions were analyzed to determine the thermal deformation of “S” testing specimens. The cutting temperature field model was based on the heat distribution ratio for the tool-workpiece contact area. The intermittent cutting temperature model was based on the actual cutting process by combining heat sources, the heat distribution, and temperature measurements. The cutting heat distribution was optimized and the coolant application was simplified to a simple forced convection heat transfer coefficient. These boundary conditions were used in a finite element simulation of the cutting heat in “S” test specimens with the results verified against temperature measurements using thermocouples on a Parpas-PM20 five-axis computer numerical control (CNC) machine tool.
