With its unique properties, Toolox 44 is one of the appropriate materials among hot work tool steels for production of extrusion dies and engineering components. However, owing to the high strength properties, machinability of Toolox 44 is a challenging issue. Therefore it is critical to determine the optimum machining parameters in milling in order to minimize machinability characteristics such as cutting forces. In this work, experiments were performed under dry cutting conditions applying four cutting speeds (150-180-210-240m/min), four feed rate (0.4, 0.8, 1.2, 1.6 mm/teeth) and two depth of cut values (0.2-0.4 mm). According to the obtained results, cutting speed and depth of cut seem as the most effective parameters on cutting force, followed by feed rate. In addition to that, first level of the cutting speed and depth of cut should be selected to the minimization of cutting force. In sum, the findings help to the researchers and industries for a specific workpiece material as providing a guide for the best machining environment.
