介绍了在大应变挤压加工中，刀具前角对切屑形成的影响。用不同前倾角挤压加工纯铜零件的实验验证了模拟研究，并对加工后的切屑进行了组织和力学性能的表征。模拟和实验结果均表明，前倾角对变形场参数和切削力有显著影响。与纳米结构材料的形成相关，一次变形区的晶粒细化是由于施加了较大的应变。而已加工切屑硬度的增加是由于晶粒度减小的结果。
This paper describes how tool rake angle affect the chip formation during large strain extrusion machining. The simulation studies were corroborated by experiments where pure copper workpieces were extrusion machined using different rake angles and the machined chips were characterized for microstructure and mechanical properties. Both simulation and experimental results showed that rake angle had a significant effect on deformation field parameters and cutting force. Associated to the nanostructured materials formation, grain refinement in primary deformation zone is due to the larger strain imposed. And the increase in hardness in machined chips was a consequence of the reduced grain sizes.
