Study on Surface Roughness of Milling Based on the Elastic-Plastic Deformation

Abstract:

In order to achieve the work-piece surface quality control, Based on the formation mechanism of surface roughness and generating mechanism of material’s surface, considering the tool parameters and feed per tooth, to modify the maximum residual height’s formula of surface. Based on formation characteristics of machined surface and the elastic-plastic deformation theory of work-piece material, Got a simplified model of the elastic-plastic deformation of the work-piece surface,and according to the molecular-mechanical friction theory ,the calculation method was presented to investigate elastic-plastic deformation of machined surface . By combining the surface residual height calculation formula with the calculation method of elastic-plastic deformation, has built the theoretic model of the milling surface roughness , can forecast to the work-piece surface roughness, as well as provide theory basis for the selection of cutting parameters and optimization.
