During high speed milling hardened steel, the problem that tool vibration reducing machining surface quality causes led to a research for the influence characteristics of milled surface topography through high speed milling experiment. To determine the formation condition of milled surface topography, using displacement increment of origin of tool coordinate system which is caused by the milling cutter vibration and installation error, modifies the cutting motion trajectory. Based on the tool-workpiece contact relationship and the cutting layer parameters of contact points on two teeth, the residual units of machined surface are established, thereby proposing a solution method for the deformation and distribution characteristic of residual units under the overhanging volume and the vibration. Therefore, the milled surface topography of cutting hardness steel with high speed ball-end milling cutter is revealed to bring out a striking contrast between the simulation and experiment of milled surface topography of hardness steel.
