根据工程仿生学原理,在硬质合金刀片上,通过激光加工的方式制备出具有凹坑表面的仿生非光滑刀具,并与光滑表面刀具在数控机床上进行了正交车削对比试验,并对切削力、切削温度和微观过程详细深入的研究。验证仿生耐磨工具在金属切削过程中的减摩效果,从切削力和切削热两个方面讨论了工具表面非光滑形态减摩效果和参数之间的关系,揭示了仿生耐磨减摩工具的基本原理,为切削钛合金过程中的仿生刀具的选择提供依据。结果表明,仿生非光滑表面刀具的耐磨附性能明显优于光滑表面刀具。
According to the principle of engineering bionics, a biomimetic non-smooth tool with a concave surface was prepared by laser processing on a carbide blade and compared with a smooth surface tool on a CNC machine tool for orthogonal turning. Force, cutting temperature and microscopic process in-depth study. The antifriction effect of bionic wear-resisting tool in metal cutting process was verified. The relationship between non-smooth surface friction reducing effect and parameters was discussed from two aspects of cutting force and cutting heat. Fundamentals, to provide a basis for the choice of bionic knives in the process of cutting titanium alloy. The results show that the wear resistance of the bionic non-smooth surface tool is obviously better than that of the smooth surface tool.
