摘要:

利用有限元分析软件ABAQUS研究微织构PCBN刀具车削Cr12MoV的过程,采用田口法进行正交试验设计,通过信噪比分析方法研究刀?屑实际接触面积、切削力和切削温度随织构参数的变化规律,并获得织构参数的最优组合。结果表明,刀?屑实际接触面积分别随织构槽宽和织构刃边距的增大而减小,织构槽宽和织构刃边距对刀具的切削性能影响最显著;与无织构刀具对比,选取最优织构参数组合的微织构PCBN刀具可使切削力降低5.2%,切削温度降低4.7%。

Abstract:

Finite element analysis software ABAQUS was used to study the process of micro texture PCBN tool turning Cr12MoV, Taguchi method was used to carry out orthogonal experimental design. The variation law of the actual contact area between tool and chip, cutting force and cutting temperature with texture parameters was studied by signal?to?noise ratio analysis method, and the optimal combination of texture parameters was obtained. The results indicate that the actual tool?chip contact area decreases with the increase of texture groove width and texture edge pitch respectively. Texture groove width and texture edge pitch have the most significant influence on cutting performance of the tool; Compared with the non?textured tool, the micro?textured PCBN tool with the optimal texture parameter combination can reduce the cutting force by 5.2% and the cutting temperature by 4.7%.

Key words: PCBN, Texture parameters, Taguchi method
