Influence of path on the ultra-precision polishing process of titanium alloy Ti6A14V

Due to the superior properties of titanium alloys, there are more and more applications of the ultra-precision situations. Nevertheless, the machinability of titanium alloys in the ultra-precision machining is still very poor. To investigate the effect of ultra-precision polishing path on the surface quality of titanium alloy Ti6A14V, a series of ultra-precision polishing tests of titanium alloy have been carried out after the ultra-precision turning tests. The results proved that the better surface quality can be obtained using the zigzag path in the ultra-precision polishing of titanium alloys. In addition, the finite element model (FEM) has been presented to simulate the press distribution and elastic deformation of the polished surface. The results of simulation proved that the zigzag path can increase the press and deformation on the workpiece.
