Abstract
In the respect of ultra-precision manufacturing of axisymmetric surface, the machine tool with tool swing feeding which has less interpolation error sources compared to the conventional ultra-precision diamond turning machine tool with T-structureis worth studying.Therefore,based on the dynamic simulation modeling and multi-body dynamics theory,in this paper, we establish the control model,and tool path for Ultra-precision machine.Then we got the model for surface topography with differentinput parameters like spindle speed, feedrate, tool parameters and so on. Taking the spherical optics part with diameter of 300 mm, for example, we input the process parameters and get its surface topography, then evaluate its surface quality by surface roughness value (Ra) and surface shape accuracy(PV) .
