Optimal Machining Strategy Selection In Ballend Milling

In the present study the groups of cutting conditions that minimize surface roughness and its variability are determined in ball-end milling operations. Design of experiments is used to define experimental tests performed. Semi-cylindrical specimens are employed in order to study surfaces with different slopes. Roughness was measured at different slopes corresponding to inclination angles .
