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.

Based on analyses of cutting heat and temperature in high speed milling, to construct a model of critical cutting speed for high speed milling cutter, find out influencing factor of critical cutting speed, and put forward optimization method of high speed milling cutter based on critical cutting speed. The results indicate that chip conducts a majority of cutting heat along with increase of cutting speed, feed speed and the rake of cutter. Cutting heat which workpiece conducts gradually diminishes when heat source accelerates. When cutting performance of cutter satisfies requirements of high speed milling, the proportion of cutting heat which workpiece conducts approaches its maximum as cutting speed comes to critical cutting speed. To optimize high speed face milling cutter for machining aluminum alloy according to critical cutting speed, the cutter takes on better cutting performance when cutting speed is 2040m/min~2350m/min.
