| Research Abstract |
In this research work, a generating method of surface patterns on finished surface of molds in ball-end milling by a 5-axis controlled machining center is analyzed theoretically and experimentally.
It is found that the angular position of the cutting edge of a ball end mill can be controlled according to the proposed algorithm in which the traverse time along the tool path is precisely calculated based on the NC data. It is shown that the finished surface with arbitrary patterns can be generated by adjusting the eccentricity of the axis of *he ball end mill and by controlling the tool path. The relationship between the eccentricity and the angular position of the cutting edges of the ball end mill has been investigated.
The factors that affect the surface patterns generated on cylindrical or spherical surfaces are investigated. From the experimental and simulated results, the fled speed is affected by the number of blocks of the NC data. It is found that the surface pattern on those surfaces can be controlled by the proposed method considering actual feed speed.
