仿生摩擦学研究表明在刀具表面置入微织构纹理可以改善外圆车刀在切削时的摩擦状况,但是置入的微织构纹理会对刀具的结构强度产生一定的影响。针对微坑织构、凸包织构和条纹织构纹理进行了刀具的建模并利用ANSYS/Workbench对不同微织构纹理刀具进行有限元分析。结果表明:在微织构的深度、间距尺寸一致的情况下,微坑织构纹理对刀具的应力影响程度较大,条纹织构纹理的影响程度较小,3种织构纹理对刀具的变形影响相差不大,综合比较条纹织构对刀具强度影响较小。
Biomimetic tribological studies have shown that the micro-texture on the tool surface can improve the friction of the cutting tool during cutting, but the embedded micro-texture will affect the structural strength of the tool. Aiming at the micro-pit texture, the convex hull texture and the striped textured texture, the tools were modeled and the ANSYS / Workbench was used to analyze the different textured micro-textured tools. The results show that the micro-pit textured texture has a greater influence on the stress of the tool and less influence of the striped textured texture when the depth and spacing of the micro-textured structure are the same. The deformation of the three textured textures The impact is not much difference, a comprehensive comparison of stripe texture on the tool intensity less affected.
