The aim of this study is to determine the effects of the different approach corners on the cutting forces in the freezing of the thermicular graphite thinning iron with TiCN and Al2O3 covered carbure cutting machines. To this goal, freezing tests were conducted in 96 different combinations in 45°, 60°, 75° and 88° approach angles with a fixed cutting depth of 2.5 mm, 180, 215, 250 and 290 m/min cutting speeds, 0.16; 0.20 and 0.24 maximum thickness in dry and wet processing conditions. Vermicular graphite thinning in dry freezing of iron increased the value of the approach angle to 45°, 60°, 75° and 88° while the cutting forces decreased. In experiments, when cooling fluid was used, cutting forces in 45° and 60° approach angles were reduced by 1,0–15,33%, while in 75° and 88° approach angles increased by 1,0–16,0%. The results of the experiment were modeled with artificial nerve networks and regression analysis. The regression model is also compared with the YSA model. This study will be useful in predicting the cutting forces that will occur during the freezing of iron.
