鏡面鋼精密拋光製程之研究

本文之目的為研究拋光路徑對表面的粗糙度變化與路徑模擬分析，測量表面粗糙度與平坦度之變化。本實驗運用電腦數值控制工具機(CNC)進行拋光路徑的控制，針對鏡面鋼進行研磨與拋光加工，並分析研磨路徑與壓力等參數的變化對鏡面鋼表面粗糙度的變化。在製造行業中拋光通常為最後一道工法也最具重要性，現今多半還是以人工的方式進行加工，並無完整的分析系統。本實驗針對鏡面鋼的研磨拋光進行分析來達到製程的預先規劃設計。實驗分析結果顯示，以鑽石研磨輪對鏡面鋼施以不同研磨路徑，螺旋研磨路徑所得到的表面粗糙度達到0.165µm為最佳路徑形式，以此路徑接著用鑽石膏來進行拋光鏡面鋼可以達到粗糙度0.01µm的表面，結果顯示研磨或拋光的路徑對於最終表面粗糙度都有重大影響。

The purpose of this paper to study the changes in the surface roughness of the polishing path and measure changes in the surface roughness and flatness. This study use of Computerized Numerical Control (CNC) for control the path of grinding and polishing process for mirrored steel and analyze changes in the grinding path and change parameters such as pressure mirrored steel surface roughness. In the manufacturing industry, the polishing is usually the last one and also the most important process, now or in the most artificial means for processing, there is no complete analysis system. Polishing in the manufacturing not only the last machining but also the most important. Now usually use artificial to machining no complete analysis system. The experiment was analyzed for mirrored steel grinding and polishing to achieve the planning and design process. Diamond grinding wheel for grinding steel mirror is subject to different paths. Experimental analysis showed that spiral path resulting surface roughness of 0.165μm to form the best path. grit diamond using a spiral path to a polished mirrored steel can reach surface roughness of 0.01μm. The results show that the grinding or polishing of the path to the final surface roughness has a significant inference.
