This research first analyzes the technical challenges in the process of machining complex free-form surface parts using ultra-precision slow tool servo turning.Then,research focuses on the surface characteristics of free-form surface parts,the extrac-tion of key parameters of surface parts and the correlation between surface parameters and tool parameters.Furthermore,the method to determine the geometric parameters of ultra-precision slow cutter servo turning diamond tool is established.Based on the analysis of the machinability of free-form surface parts,the selection criteria of diamond tools in ultra-precision slow cutter servo turning were established.Finally,through the experiments of ultra-precision slow tool servo turning and the analysis of the actual cases of ultra-precision slow tool servo turning,it is proved that the part surface analysis model established and the reason-able selection of diamond tool geometric parameters are of great importance to the realization of efficient and stable industrial ul-tra-precision slow tool servo turning.
