| 摘 要： | 建立了淬硬钢精密切削加工表面粗糙度预测模型;采用PCBN刀具对GCr15淬硬钢进行了正交切削优化试验,获得了相当于精磨加工的表面粗糙度;试验结果表明进给量和刀尖圆弧半径是影响PCBN刀具精密硬态切削表面粗糙度的主要因素。研究可为精密硬态切削工艺参数的选择提供参考和依据。

| Abstract: | The prediction model of surface roughness for hardened steel turning has been established.Through optimization of orthogonal hard turning test by using PCBN tools,the surface roughness of hardened bearing steel GCr15 equals that of fine grinding processing.The results show that feeding and corner radius are the most important factors which affect the surface roughness in precision hard turning by using PCBN tools.This research could provide reference for the selection of process parameters in precision hard turning. |
