Paper Title:
SSA Based Decomposition of Tool Position Trajectory for Diamond Turning of Freeform Optical Surfaces
  Abstract

The radial spiral feed of the tool and the tool nose radius compensation are taken into consideration for the tool position trajectory (TPT) generation in diamond turning of freeform optical surfaces. Using the coarse sampling and the fine interpolation, a novel approach based on singular spectrum analysis (SSA) is presented to decompose the generated TPT into a slowly varying trend and a quickly varying quasi-periodic oscillation. The numerical experiments of the TPT decomposition of toroidal surfaces have been carried out. The results verify that the proposed approach is very effective for the TPT decomposition.
