A Model of Stress Distribution in Tool-Chip Contact Zone Machining

LI Min1,ZHAO-Gang2,LIU Li-qiang3 (1.Harbin Vocational Institute of Technology,Harbin 15001,China;2.The 4th Teaching Room of Dalianwan Group,Dalian116113,China;3.Jiamusi University,Jiamusi 154007,China)  
The cutting performance,cutting temperature and tool wear are influenced by the stress distribution of tool-chip contact zone.In this paper,through the cutting force analysis and computation of tool-chip contact length in orthogonal cutting process,the model of normal stress and shear stress distribution are developed in the tool-chip contact zone,and the stress distribution can be computed directly using this model.
