Research on the optimal cutting parameters for ball end finish milling process of complex surfaces

The purpose of the present paper is to determine recommendations for complex surface finishing operation with ball end mill. The parameters that influence the roughness are: (i) technological parameters (such as step), (ii) geometrical (radius of milling cutter, angle of surface inclination or tilt angle) and (iii) cutting strategy. Paper presents roughness calculation theory and provide comparison of simulation and experimental data. Finally, recommendations to obtain desirable value of the roughness are given in the paper.
