A lot of studies on the tool-path generation for five-axis controlled machining centers have been reported. However, the finished surface roughness has not been considered. For reducing the hand-finishing process of molds, it is great important to control the texture of finished surface. Especially, the surface texture finished by means of five-axis controlled machining centers is a significant factor to reduce the production time. In this research work, the generation mechanism of the surface texture is analyzed theoretically and experimentally. In the experiment, the eccentricity of the tool axis and the angular position of the cutting edges of the ball end mill are controlled according to the proposed algorithm in which the traverse time along the tool path is calculated precisely. From the experimental and theoretical results, it is found that the surface texture can be controlled by the proposed method.
