During a turning process, heat is generated at the edge of the cutting tool. This heat is then dissipated through the four systems that make up the process which are the cutting tool, the workpiece the chip formed and the cutting fluid. This heat, either generated or dissipated, can be said to determine the efficiency of the machining process such as the material removal rate. In this project, the study about the effect of depth of cut and cutting speed that influence the temperature at the workpiece surface. The experiment was conducted by a turning machine. Then the temperature of the workpiece surface is measure by using infrared thermograph camera. The workpiece for the experiment was S45C medium carbon steel. As observed from the conducted experiment, the results showed that the depth of cut have a significant effect over temperature on the workpiece surface. Contradictory results were obtained for cutting speed over temperature. The increase in cutting speed reduced the temperature on the workpiece surface.
