【摘要】 具有微纳结构的功能表面越来越多的应用于先进光学、先进制造等领域。为了实现微纳结构表面的批量制造,对铁基模具材料微纳加工技术的研究变得尤为必要。由于剧烈的刀具热化学磨损,普通的金刚石切削技术很难用于铁基材料的微纳切削加工。近年来,椭圆振动金刚石切削技术已成功应用于模具钢的超精密切削加工。本文实验验证了铁基材料椭圆振动金刚石镜面切削能力和极小的刀具磨损量。随后将可控振幅椭圆振动雕刻技术应用于微纳结构的车削成型过程,成功获得铁基材料的正弦波、三角波和方波功能表面。更多还原

【Abstract】 ;The functional surfaces with the micro/nano structures have been applied to the advanced optics and manufacture engineering.In order to obtain the mass production of the above mentioned micro/nano structures,it is necessary to carry out the investigations of micro/nano machining of the mold materials,especially the steel material.However,it is difficult to apply the ordinary diamond cutting technology to the steel material machining due to the serious thermal-chemical tool wear.Recently,the hardened steel has been successfully machined by applying the elliptical vibration cutting with the single crystal diamond tool.In this paper,the precision machining of steel material is firstly carry out by applying the elliptical vibration cutting technology.The tiny diamond tool wear was experimentally confirmed.Following that,the micro/nano structures,i.e.,sinusoidal,triangular and square structures,are successfully fabricated by applying the amplitude control sculpturing method in the elliptical vibration cutting process.更多还原
