目的 研究切屑形成机理对加工过程的影响。方法 超声振动辅助车削技术通过刀具振动的拟间歇切削特征控制切屑尺寸和切屑形态,从而提高了加工表面质量。针对SiCp/Al复合材料的切屑形成机理,探究常规车削和超声振动辅助车削的切屑形成过程。研究了颗粒分布对第一变形区变形阶段的影响,以及不同加工方式下切削参数对切屑形态的影响。最后,描述了切屑自由表面和刀-屑接触界面的颗粒损伤形式,以直观地描述常规车削与超声振动辅助车削SiCp/Al复合材料加工中切屑的形成过程。结果 通过测试加工后工件表面形貌发现超声振动辅助车削的切屑更加连续、切屑尺寸较小的加工表面粗糙度更小,常规车削的表面粗糙度为0.805 μm,超声振动辅助车削的表面粗糙度为0.404 μm,超声振动辅助车削比常规车削的表面粗糙度降低了49.8%。结论 与常规车削相比,超声振动辅助车削有利于减小切屑厚度。超声振动辅助车削得到的切屑更加连续,避免了切屑碎裂,促进了切屑的顺利排出。通过对切屑形态进行研究,选择最优切削参数可以有效提高工件表面质量。 |
