Outline of Research at the Start

近年,医療・光学関連など様々な分野で精密部品の微細化への需要が拡大しており,それらの発展に伴い,微細部品の表面にダメージを与えずかつナノレベルに仕上げる精密研磨技術が求められている.本研究は,変動磁場を利用した超精密加工法を提案し,微小磁性砥粒の動きの変動によって超精密表面創成に着目し,微細複雑形状部品の表面仕上げを実現することを目的としている.また,磁気研磨スラリーはミクロンサイズの磁性粒子を利用するため,微細複雑形状部品の表面にダメージを与えずかつナノレベルに仕上げることができる.本研究によって提案する加工法の有効性を示すとともに,産業界に応用する可能性を検討し,実用化を目指す.

Outline of Final Research Achievements

Precision machining technology that can finish parts with complex micro-shapes to a nano-level without damaging the surfaces is in demand in various industrial fields. In this study, we proposed an ultra-precision machining method that utilizes an alternating magnetic field, in which the active movement of magnetic particles in the alternating magnetic field is linked to the abrasive grains, enabling precision machining while dispersing the particles. Magnetic field analysis was used to determine the optimal magnetic field configuration, and the formation and operating conditions of the dynamic magnetic brush generated by the magnetic finishing slurry in an alternating magnetic field were clarified. In addition, in order to realize surface finishing of parts with complex fine shapes, a new processing device using a 6-axis robot was developed toward practical application. Detailed finishing experiments were carried out, and the usefulness of this processing method was proved.
