In order to find out the formation of micro-waves on the fly-cut surface, the spindle motion error is sampled and a 3D topography simulation model is compiled. Firstly, a nano-class testing and evaluation system is established on the fly cutting machine, the displacement data is sampled and the spindle motion error is analyzed. Then a 3D surface profile topography simulation model is established to analysis the micro-waves caused by the spindle motion error, The simulated surface is compared with the measured surface，and find out the error sources. Finally, the characteristics of spindle is improved by adjust the control system of spindle motor. The simulated 3D surface profile topography approximated to that of measured profile, this verifies that the macro-waves is caused by the undulate of the spindle speed, When the spindle characteristics was improved, the macro-waves caused by the spindle motion error was almost disappears, the surface roughness reduced from more than 5nm to 2nm. Thus, the undulate of ultra-precision fly cutting machine spindle speed will cause macro-waves on the workpiece surface, and the undulate spindle speed must less than 0.5rpm.
