Development of cutting tool with functional surface by nano/ micro texture

为了提高刀具的抗粘着性能和耐磨性，我们采用了表面工程的方法，即通过纹理对刀具表面进行功能化。为提高铝合金干切削时的抗粘着性能，本研究开发了具有微条纹织构的刀具。结果发现，新开发的刀具显著降低了刀具前刀面上的切屑附着力。此外，还对所研制刀具的耐磨性进行了评价。

In order to improve cutting tool performances including anti-adhesive property and tool wear resistance, we have adopted surface engineering approach, namely, a functionalization of tool surfaces by textures. In this study, cutting tool with micro stripe texture was newly developed to improve anti-adhesion in dry cutting of aluminum alloy. As a result, we found that the newly developed tool significantly decrease chip adhesion on the tool rake face. In addition, the tool wear resistances of developed tools were also evaluated.
