我们提出了具有各种纹理表面的切削刀具，以延长切削刀具的寿命。我们前期的研究开发了采用飞秒激光技术在前刀面上形成周期性条纹沟槽的切削刀具，在切削钢材时表现出较高的抗月牙洼磨损性能。本研究对抑制刀具表面月牙洼磨损的机理以及织构尺寸与耐磨性之间的关系进行了研究，为开发具有织构表面的刀具提供了指导。此外，我们在切削工具的后刀面中新引入了纹理表面，以提高后刀面耐磨性。对钢材进行面铣实验表明，新开发的具有纹理后刀面的刀具显着降低了后刀面磨损。此外，还讨论了织构尺寸和切削条件对后刀面耐磨性的影响。 (C) 2013 Elsevier Inc. 保留所有权利。
We have proposed cutting tools with various textured surfaces to increase cutting tool life. Our previous studies have developed cutting tools having periodical stripe-grooved surfaces on their rake face formed using femtosecond laser technology, which displayed high crater wear resistance in cutting of steel materials. In this study, the mechanism for suppressing the crater wear on the tool surface and the relationship between texture dimensions and wear resistance were investigated to provide a guideline for developing tools with textured surfaces. Furthermore, we newly introduced the textured surfaces into a flank face of cutting tools to improve flank wear resistance. Face milling experiments on steel materials exhibited that the newly developed tool having the textured flank face significantly reduced the flank wear. Moreover, the influences of texture dimensions and cutting conditions on the flank wear resistance were also discussed. (C) 2013 Elsevier Inc. All rights reserved.
