Sažetak

In the study, the influence of rake angle, clearance angle, inclination angle, approach angle and nose angle on the dimensional deviation and roughness of the machined surface during dry turning of Ti6Al4V alloys was investigated. The experimental investigation utilized a custom design of experiments. The results indicated that the dimensional deviation varied between 0.053 mm and 0.081 mm, while the surface roughness ranged from 1.892 mm to 2.141 mm, depending on the different combinations of insert angles. An analysis of the results showed significant effects of both the main and quadratic interactions of the input parameters on the output parameters. Notably, altering the angles of the cutting insert affected dimensional deviation by 52.83% and surface roughness by 13.16%. Additionally, a strong correlation was found between the output parameters. Confirmation experiments were conducted to validate the developed predictive equations, and the percentage errors demonstrated the accuracy of the modelling process.
