摘要
针对汽轮机A880高压动叶片型面粗加工切削性能进行试验,实时监控切削力,并开展基于切削力频谱分析的切削参数优化研究。结果表明,切削力时域信号和频域信号能够有效反映切削性能和切削稳定性,基于切削力频谱分析方法为提升叶片制造水平提供试验依据。
Experiments investigation were conducted on the machinability when ball milling A880 gas turbine blade profile. Cutting force spectrum acquired online were used to optimize the cutting parameters. The results indicates that cutting force signal in time domain and frequency domain can reveal the cutting stability, which provides an experimental guideline for gas turbine blades manufacturing.
