织构分布对刀具切削性能影响的有限元分析
Finite Element Analysis of Texture Distribution on Tools Properties
摘要
Abstract
The work aims to study the effects of surface texture distribution on tools machinability. Finite element simula-tion of TI6AL4V was completed by using a 2D model based on the large-scale nonlinear analysis software ABAQUS, cutting force data was collected and verified based upon cutting experiments, finite element simulation of equispaced, non-equispaced and mixed texture were done once errors was qualified, and cutting data such as cutting force and cutting heat was collected for analysis. Compared with texture-free cutting tools, maximum temperature of equispaced texture tool decreased by 12.4%, that of non-equispaced texture cutting tool by 14.5%, and mixed texture tool by 16.5%. Compared with texture-free tools, principal cut-ting force of equispaced texture tool decreased by 9.8%, that of non- equispaced texture tool by 11.2%, and mixed texture tool by 12.6%. Proper surface texture can improve machinability of tools, the smaller the distance between the texture is, a more ob-vious role will texture plays in reducing friction. Antifriction effect of the non-equidistance texture was better than that of equispaced texture. Too dense texture leads to vibration during cutting. Adding smaller superfine texture in microtexture can not only reduce contact area of tool chip, but also avoid tool strength decrease as a result of undersize gap.关键词
