1) Back cutting depth
背吃刀量
1.
Based on the ultra precise turning experiments, the influences of feeds and back cutting depth on the cutting force in micro thin cutting are analyzed.
通过超精密车削试验 ,分析了微薄切削时进给量和背吃刀量对切削力的影响规律 ,指出吃刀抗力Ft的特殊变化将直接影响加工表面粗糙度 ,为保证超精密加工表面质量 ,应在合理范围内选取刀具进给
2.
Even if the date of back cutting depth is bigger in the parts of cutting velocity, the cutting system\'s chatter vibration might not be happened.
如果公称切削速度处于该稳定区域,即使背吃刀量较大,系统也不易发生颤振。
2) limit back engagement
极限背吃刀量
1.
To counter the theoretic analysis of the drinimum limit back engagement, thechip - breaking lindt curve is analyzed systematically and the theoretical computation formula of the3D side-curling diip section parameters was constructed in this paper, on the basis of which thedrinimum lindt back engagement is theoretically analyzed and the theoretic computation formulahas been deduced.
针对最小极限背吃刀量的理论分析问题，对切屑折断曲线进行了系统分析，建立了三维切削横向卷曲截面参数的理论公式；推导了最小极限背吃刀量理论计算公式，并通过迭代计算得出近似的CD部分曲线，求导后得出最小极限背吃刀量，与实验结果符合很好。
