在这项研究中开发了在其表面上具有微米级或纳米级纹理的新型切削工具。在固体表面上纹理化微米级或纳米级特征使我们能够控制工具的摩擦学特性。在这份报告中，类金刚石碳（DLC）涂层的纹理的工具，开发使用飞秒激光和随后的DLC涂层方法。通过施加DLC涂层，在没有工件材料粘附的情况下评估了纹理的影响，因为其粘附率低，并且还可以研究纹理在涂层工具上的应用。在不同的切削条件下对铝合金进行了车削试验。结果发现，潮湿的条件是适合的开发工具和进一步降低切削力时，观察到的纹理施加到DLC涂层刀具。织构方向的变化趋势与未涂层的织构刀具相似，表明织构效果的差异不仅取决于工件材料的附着特性，还取决于其他因素。即使在低切削速度下也能观察到织构的影响。这些结果表明，毛化刀具适用于DLC涂层刀具。
Novel cutting tools that had either microscale or nanoscale textures on their surfaces were developed in this study. Texturing microscale or nanoscale features on a solid surface allowed us to control the tribological characteristics of the tool. In this report, diamond like carbon (DLC) coated tools with the texture were developed using a femtosecond laser and subsequent DLC coating methods. By applying DLC coating, the effects of the texture were evaluated without adhesion of a work material due to its low adhesion rate and application of the texture to coated tools can also be investigated. Turning experiments of aluminum alloy were performed under the various cutting conditions. It was found that the wet condition was suitable for the developed tool and the further decrease in cutting forces were observed when the texture was applied to the DLC coated tools. The tendency of the direction of the texture was similar to that of the noncoated textured tools, which indicates that the difference in the effect of the texture was decided not only by the adhesion characteristics of the work material but also by other factors. The effects of the texture were observed even at the low cutting speed. These results indicate that the textured tool is applicable for the DLC coated tool.
