切割元件刃口的微观几何形状影响到滑切和斜切的切割过程。在依凡希科的大部分著作中阐述了这一点。他尤其注意到以往的见解,即切割器刃口的锯齿形状对滑切的重要作用。他认为,只有刃口的锯齿形状,才对切割过程具有决定性的作用,而其他的刃口质量(锐利程度、刃磨角等)可以略而不计。 The microscopic geometry of the cutting edge affects the slitting and chamfering processes. This is illustrated in most of Ivshiko’s book. In particular, he noticed the previous observation that the serrated shape of the cutting edge plays an important role in slip-cutting. He believes that only the serrated shape of the cutting edge, the cutting process is decisive role, and other cutting edge quality (sharpness, sharpening angle, etc.) can be negligible.
