Abstract

Multi- Axis ultra-precision machining plays an important role in manufacturing freeform surface and microlens arrays. In this paper, a 6- Axis positioning system, Hexapod, is modified to be used as a tool holder that can be attached to mid-range turning machines to improve their repeatability to sub-micrometric level. A novel tool path generation method utilizing 6 axis motion was designed to improve the surface finish by adapting the unique movement pattern of a hexapod and by attaining surface normal cutting through adjusting the orientation of the diamond tool. The face turning and compound eye cutting experiments were conducted to verify the performance of the tool holder system and tool path generation algorithms. Experimental results show that the form error and surface roughness of the specimen machined by the proposed tool holder could attain the sub-micrometric level.
