Surface Topography Model of Ultra-High Strength Steel AF1410 Based on Dynamic Characteristics of Milling System

AF1410 is a low carbon high alloy ultra-high strength steel. It not only has and toughness, but also stress corrosion resistance. However, due to the characteristics of hard quality poor thermal conductivity, difficult material process. In process milling, geometric factors parameters, flexible deformation milling cutter flutter system all affect surface roughness, which makes it predict roughness parts. order solve this problem, prediction model for topography ultrahigh steel was studied. To paper studies formation topography, considers dynamic displacement system, proposes modeling method based on forms model. On basis, simulated analyzed, accuracy verified by experiments. The study realizes parts reveals mechanism from physical perspectives.
