Blade integrated disk, also known as blisk, are generally produced on multi-axis machines due to their complex geometry and their need to be produced using difficult-to-machine materials that meet high mechanical/thermal performance expectations. In the processing of variable, small, and narrow-section blade geometries, it is aimed to increase the cutting tool’s performance by reducing the cutting force, resultant bending moment, torsional moment, and lost time. Within the scope of this study, changes in forces and moments depending on the cutting speed and feed rate in the milling of 17–4 PH stainless-steel with advanced material properties using a barrel-shaped cutting tool capable of operating simultaneously in 5 axis and designed for use in finishing processes were experimentally investigated, and the results that were obtained were statistically analyzed. For this purpose, the effects of 3 different cutting speeds (26.3, 29.8, and 36.1 m/min) and 3 different feed rates (0.0175, 0.025, and 0.035 mm/tooth) were investigated in experiments, and the obtained data were statistically analyzed by analysis of variance (ANOVA). As a result, while the parameter affecting the cutting forces the most was the cutting speed, it was observed that the feed rate was the most effective machining parameter on the resultant bending moment and torsional moment, and the tool path had a significant effect on machining performance. The most suitable machining parameters were determined as a 29.8 m/min cutting speed and a 0.025 mm/tooth feed rate, at which values the cutting force was 25.86 N, the bending moment was 2.02 Nm, and the torsional moment was 0.078 Nm.
