本文以硬质合金刀片为研究对象,设计了一套完整的车-车梳模拟切削工艺,在该工艺中确定了每一个工序的工件状态、对应使用的刀片型号及其走刀路线。经过一定的分析,确定了每种刀片所侧重的切削性能,以此为优化标准来安排切削实验。分别对R型刀片和C型刀片进行了断屑实验,通过收集切屑分析两种刀片的断屑效果;对V型刀片和梳型刀片进行了粗糙度实验,采用RA-200型号的电感式粗糙度仪进行粗糙度测量。实验切削参数的选择由企业推荐参数为中心向前后扩展。实验后以每种刀片所侧重的优化性能为参考选出了最佳的切削参数组合,各刀片对应的最优切削参数分别为:R型刀片Vc=120 m/min,f=0.35 mm/r;C型刀片Vc=180 m/min,f=0.35 mm/r;V型刀片Vc=180 m/min,f=0.3 mm/r;梳型刀片Vc=260 m/min,f=0.15 mm/r。
In this paper, a complete set of car - car comb simulation cutting technology is designed for the cemented carbide insert. In this process, the workpiece status of each process is determined, and the corresponding insert type and its routing are determined. After a certain analysis, to determine the focus of each blade cutting performance, as an optimization standard to arrange cutting experiments. The chip breaking experiments on R-type and C-type blades were carried out respectively. The chip breaking effects of the two kinds of blades were analyzed by collecting the chips. The roughness experiments of the V-shaped and comb-type blades were carried out. The roughness of the R- Roughness measurement instrument. The choice of experimental cutting parameters by the enterprise recommended parameters as the center to the front and rear expansion. After the experiment, the best combination of cutting parameters was selected based on the optimal performance of each blade. The optimum cutting parameters of each blade were: Rc = 120 m / min, f = 0.35 mm / r ; V-shaped blade Vc = 180 m / min, f = 0.35 mm / r; V-shaped blade Vc = 180 m / min, f = 0.3 mm / r
