This paper presents an experimental study of dry longitudinal single–pass turning of X155CrVMo12–1 steel using two cutting inserts with different rake angles. Initially, the model based on dimensional analysis was developed to estimate the main cutting force, while considering three dimensionless groups with six parameters. After experimental validation, the developed dimensional analysis-based model was further for the analysis of the cutting energy and specific cutting energy. Detailed analysis included the analysis of the effects of feed rate, depth of cut and rake angle on considered process performances. The observed correlations between cutting parameters and process performances were compared with the previously published experimental results. It has been observed that the depth of cut has the greatest influence on the main cutting force and cutting energy, while the feed rate has a slightly more pronounced effect on the specific cutting energy.
