In the ball-end milling, the surface roughness along the feed direction must be considered when feed per tool revolution was increased. However, if the surface pattern can be controlled, it is possible to use the pattern for industrial design and to reduce the hand-finishing process of molds. In this research work, the generation mechanism of the surface pattern on a curved surface is analyzed theoretically and experimentally. In the experiment, the angular position of the cutting edge of the ball-end mill is controlled according to the proposed algorithm in which the traverse time along the tool path is precisely calculated. From the experimental and theoretical results, the feed speed received the effect between number of blocks and distance between blocks. It is found that the surface pattern on cylindrical and spherical surfaces can be controlled by the proposed method considering actual feed speeds.
