摘要:

构建无织构刀具和呈微凹坑、平行槽、垂直槽、斜向槽形貌的微织构刀具模型,并利用有限元分析软件ABAQUS研究了微织构刀具对钛合金车削过程的影响。通过分析不同形貌微织构刀具在切削过程中的切削力、摩擦系数、切削温度和工件表面残余应力,确定了较优的微织构形貌;研究了切削速度对微织构刀具切削钛合金性能的影响。结果表明,微织构刀具能有效降低切削力、摩擦系数和切削温度,使工件表面残余应力由拉应力转变为压应力,其中垂直槽微织构刀具能最有效地改善切削质量;随着切削速度的提高,切削力和切削温度增大,摩擦系数减小,工件表面残余应力由压应力向拉应力转变并有增大的趋势。

Abstract:

A model of a micro-texture tool featuring various textures such as micro-pits, parallel grooves, vertical grooves, and oblique grooves was developed. The impact of these micro-texture tools on the turning process of titanium alloy was investigated using the finite element analysis software ABAQUS. Through an examination of cutting force, friction coefficient, cutting temperature, and surface residual stress for micro-texture tools with distinct morphologies, the optimal micro-texture morphology was determined. The findings reveal that micro-texture tools can effectively reduce the cutting force, friction coefficient, and cutting temperature while transforming surface residual stress from tensile to compressive on the workpiece. Furthermore, with increasing cutting speed, cutting force and cutting temperature rises, friction coefficient decrease, and the residual stress on the workpiece surface shifts from compressive to tensile stress, exhibiting an ascending trend.

Key words: ABAQUS, Micro-texture tool, Titanium alloy, Cutting speed, Cutting performance
