Abstract

Abstract

Residual stress caused by machining has always been the focus of manufacturing field. The surface residual stress state can reflect component performance and service life. In order to better understand surface and subsurface residual stress state of milled parts, the milled undeformed cutting thickness of unequal thickness was converted into the undeformed cutting thickness of equal thickness for micro milling force modeling. A 2D equal thickness undeformed cutting thickness model established by simulation was used to study the temperature when cutting titanium alloy, the surface residual stress after milling was predicted by combining the microelement force and temperature model, and predicted value, simulated value and measured value of residual stress were compared. The results show that the variation trend of simulated value and measured value of residual stress is basically the same, and the proposed residual stress prediction model established by equal thickness undeformed cutting thickness can reflect the surface stress state.
