在连续切削中，在刀具前刀面上形成粘接剂，以粘接剂的形式作为保护层，继续切削。在切削开始时，涂层表面的粘着磨损和磨粒磨损都在进行。另一方面，在断续切削时，当刀具零件脱离工作时，前刀面上的粘接剂与涂膜同时形成片状。随着这些重复，工具的磨损也在增加。在切削结束时减少未变形的切屑厚度可以抑制剥落。
In continuous cutting, adhesive is formed on the tool rake face and cutting is continued while taking the form of adhesive as protective layers. At the beginning of cutting, both adhesive wear and, abrasive wear of coating film on flank progress.On the other hand, in interrupted cutting, when the tool parts from the work the adhesive formed on rake face and coating film flake at the same time. With these repetition tool wear progresses. Flaking can be restrained by reducing undeformed-chip thickness at the end of cutting.
