本文论述了在高温合金、钛合金、淬硬钢、铸铁等材料的切削加工中，log V-log L关系中存在的强非线性，这种非线性对提高切削速度下的寿命切削距离起着重要而有利的作用，即在一定的切削速度范围内，寿命切削距离随切削速度的增加而增加。通过对滑动试验和切削试验中刀具磨损的研究，发现了刀具磨损具有很强的非线性，并对非线性产生的机理进行了探讨。
This paper describes strong nonlinearity in log V-log L relationship, which is often found in machining of supperalloys, titanium alloys, hardened steels, cast irons, etc. The nonlinearity plays an important and favorable role in extension of life-span cutting distance at higher cutting speeds; that is, in a certain range of cutting speed, life-span cutting distance increases with cutting speed. Results of tool wear in a sliding test and cutting experiments, which showed the evidences of strong nonlinearity, were investigated and the mechanisms causing the nonlinearity were discussed.
