在微細加工的領域中，放電加工能夠加工直徑小於100μm的孔徑，但易產生放電坑、再鑄層與微裂痕，因此加工後的孔徑與粗糙度不盡理想，嚴重影響微孔的表面品質，而本研究為了改善放電加工所產生的缺點，擬開發利用複合電鍍沉積方式製作微研磨工具，並以高鎳合金為工件材料，期能將放電加工後的微細孔洞進行孔壁研磨加工，而獲得高精度且低粗糙度的精微孔洞，以作為精密工業之用。
實驗結果顯示，以電流為10mA、陽極環孔徑為5mm、磨粒粒徑為4μm、轉速為15rpm、磨粒添加量為10g/L與CTAB界面活性劑為150ppm等參數進行複合電鍍沉積微型研磨工具，並再以進給速度30μm/min對放電過後的微孔進行研磨加工時，可得到較光滑平整的微孔孔壁，孔壁表面粗糙度值由1.47μm Rmax (0.2μm Ra)降至0.462μm Rmax (0.026μm Ra)。 | zh_TW |

This study presents a novel process of using micro-electro-discharge-machining (micro-EDM) combined with electro-codeposition to fabricate the micro-grinding-tool to machining a micro-hole on high nickel alloy. During the machining process, a micro-grinding-tool is fabricated by wire electro-discharge grinding (WEDG) and electro-codeposition directly by using micro-EDM for machining the micro-hole and by micro-grinding to finish the hole wall.
The experimental result shows the suitable parameters obtained to fabricating micro-grinding-tool for electro-codeposition are considered to be the following: electric current of 10 mA, hole diameter of positive ring is 5 mm, SiC particle size of 4μm, SiC particle concentration of 10 g/L, rotational speed of 15 rpm and CTAB of 150 ppm. By this method, The micro-grinding-tool will provided with smoothness surface on coating layer, uniform particle distribution and suitable adhesion particle quantity. Finally, the tool feed adopts as 30 μm/min in micro-grinding process, the surface roughness reduces from 1.47 μm Rmax (0.2 μm Ra) to 0.462 μm Rmax (0.026 μm Ra) after micro-grinding. | en_US |
