摘　　要：为探索织构方向在改善刀具性能方面产生差异的原因,首先分析了前刀面织构对切削力的影响以及织构倾斜角对衍生切削的影响机理.其次采用激光加工方法在前刀面制备了具有不同方向的织构.从切削力、切削温度、刀具磨损、工件表面粗糙度和切屑形态方面比较了织构刀具切削AISI 304的性能.结果表明,织构刀具性能由织构减小的刀-屑接触面积和织构造成的衍生切削共同决定.织构倾斜角度对衍生切削具有较大影响,具有较小织构倾斜角的织构刀具切削性能最优,相较于普通刀具,切削力、切削温度和工件表面粗糙度的最大降幅分别达到了13.2%,16.7%和3.76%.To explore the reasons for the difference in the texture direction in improving the tool performance,firstly,the effect of the texture on the cutting force was analyzed,as well as the mechanism of texture direction on the derivative cutting.Secondly,the textures with different directions were fabricated by laser texturing techniques.The cutting performances of the textured tool were compared in terms of cutting force,cutting temperature,tool wear,workpiece surface roughness,and chip morphology.The results showed that the performance of the textured tool is determined by both the reduced tool‑chip contact area and the derivative cutting due to the textures.The texture direction has a large effect on the derivative cutting.The cutting performance of the tool with a smaller textured tilted angle is optimal,with maximum reductions in cutting force,cutting temperature,and workpiece surface roughness of 13.2%,16.7%,and 3.76%,respectively,compared to the untextured tools.
