中文摘要:
      目 的 研究高速干切削 工艺 对难加工材料加工表面质量的 影响规律。 方法 在切削 速度范围157 ~ 314 m /min 内 , 依据析因 试验设计方法, 对马氏体不锈钢工件进行干切削 条件下的端面铣削 工艺 试验, 考查铣削 加工表面粗糙度变化规律、表面微结构组织特征与 维氏硬度分布曲线。 结果 由每齿进给量和铣削 深度共同 决定的切屑截面构形对马氏体不锈钢加工表面轮廓的形成机制有显著作用 , 加工表面的表层及次表层组织主要由塑性变形层与 回火多 相组织层共同 构成。 结论 为 减小干式切削 对加工表面层组织特征的影响, 应优先选择大进给量、小切深的工艺参数组合。
英文摘要:
      Objective To investigate the influences of high-speed dry cutting process on the surface quality of difficult-to-cut materials. Methods Face milling experiment of martensite stainless steel was conducted at the cutting regime of 157 ~ 314 m/min in dry cutting condition under the guidance of 2K factorial design method, the characteristics of surface roughness, microstructure properties and micro-hardness distribution curves were studied experimentally. Results It was shown that: the chip cross section determined by the depth of cut and feed per tooth had significant influence on the formation of roughness profiles; severe plastic deformation and multi-phases structures were the main components of the surface and subsurface layers. Conclusion In order to reduce the negative effects of dry cutting process on machined surfaces, the cutting parameters should be carefully controlled, larger feed per tooth and smaller depth of cut are preferred.
