Ball end milling of complex surfaces is common in the mould and aerospace industries. A significant influential factor in complex surface machining by ball end milling for roughness, part accuracy and tool life is the cutting force. This work is devoted to the analysis of cutting forces and roughness parameters that arise during milling with a ball end tool with a variable surface angle (γ). A model of the cutting force and motion of the tool is formulated taking into account the inclination of the surface. The factors affecting the magnitude and nature of surface roughness during milling with a ball end tool are investigated. It has been experimentally established that the reduction in amplitude roughness parameters occurs with an increase in the inclination angle. Instantaneous values of cutting forces were measured in the range of values of variable feeding per tooth (fz) and angle of surface inclination (γ). The study showed that the forces of cutting and roughness are highly dependent on the inclination of the surface, both in quantitative and qualitative terms. This observation is also supported by the model developed. |
