中文摘要
本研究提出使用導電高分子作為之工具電極,以迴轉式電解擦光法加工不銹鋼。其加工電流、加工負荷、磨粒粒徑等實驗參數對表面輪廓與粗糙度之影響。
本實驗之工件與工具電極旋轉方向相同。當實驗條件為加工電流13.5 mA、加工負荷15 N,以純電解拋光加工不銹鋼表面,加工6分鐘後,使Rmax從0.5 μm降至0.3 μm。在一定的負荷與時間下,僅使用磨粒加工不銹鋼時,Rmax可降至0.28 μm。將電解與磨粒作用複合時,磨粒粒徑為1μm與3 μm之Rmax值分別下降為0.228 μm及0.113 μm。最後,當加工時間增至12分鐘時,可得到一平坦且光亮之不銹鋼表面,讓Rmax可下降至0.088 μm,而Ra由0.08 μm降為0.01 μm。
Abstract
In this study, a conductive polymer was used as a tool electrode to finish the stainless steel by the rotary electrochemical buffing method. The effects of current, load, and particle size on the histories of the surface profile and roughness.
In this experiment, the direction of rotation for the workpiece and the tool electrode was the same. When the operative parameters were set for the current of 13.5 mA, the load of 15 N, the surface of the stainless steel was polished using the pure electrochemical polishing for 6 minutes, so that Rmax could be reduced from 0.5 μm to 0.3 μm. Under a certain of load and machining time, when the stainless steel was polished using the only abrasive particles, Rmax could be reduced to 0.28 μm. Combining the electrochemical polishing and the abrasive machining, Rmax could be reduced to 0.228 μm and 0.113 μm for the particle sizes of 1 μm and 3 μm, respectively. Finally, when the machining time increased to 12 minutes, a smooth and bright stainless steel surfaces could obtain, so that Rmax could be reduced to 0.088
μm, and Ra from 0.08 μm to 0.01 μm.
