Abstract: Multi-axis micro-cutting machines with the parallel kinematic configuration are promising because it can reduce multiple cyclic repetitive alignment setups, and is able to adjust the pose of diamond tool during the turning process. In this paper, a micro-cutting centre is developed. The key component is the 6-axis tool holder which consists a Hexapod robot. One major problem of using the Hexapod robot to cut metals is that the its stiffness is much smaller than that of machine slides. The dynamic performances of Hexapod and machine slide are compared. It is found that although the Hexapod mechanisms induce new peaks in the PSD of thrust force, the amplitude of the vibration is insignificant in the thrust direction. Experimental results show that the surface roughness of the specimen machined by the proposed tool holder could attain the sub-micrometric level.
