The article content aims to investigate the influences of cutting modes (cutting speed, feed rate and depth of cut) on cutting force components in the hard turning process of AISI H13 steel (55 HRC). The factorial experimental design was used to investigate the effects of input factors including cutting speed, feed rate and depth of cut on cutting force components. The obtain results indicated that the feed rate causes the strongest influence on the cutting forces, while the cutting speed and depth of cut have the less impacts. The growth of feed rate values promotes the cutting forces to increase rapidly. Moreover, the hard turning process under dry environment contributes to the environmental friendly characteristics and reduces the manufacturing cost resulted from the consumption and treatment of cutting fluids.
