磨削參數對熱影響層之研究

磨削品質為加工者常常忽略卻會影響工件性能的因素，本文主要內容在研究、討論如何在相同材料移除率下提升磨削品質以及在相同品質下提升材料移除率，方法是透過高速磨削及移動熱模型的參數搭配而提出的，最後實驗結果以金相的方法檢驗，結果顯示在相同材料移除率下表面品質得以提升；在相近磨削品質可提升材料移除率，但超過一定材料移除率磨削品質開始不穩定，結果另外發現砂輪修整條件影響變質層之程度更超過其他參數的調控。

Grinding quality is the factor that a processor often overlooks but affects the performance of the workpiece. The main contents of this paper are to discuss how to improve the grinding quality under the same material removal rate and to increase the material removal rate under the same quality. The concept of Solution is based on high-speed grinding and the moving thermal model, and the results are verified by metallographic method. The results show that surface quality can be improved under same material removal rate, and the material removal rate can be increase under same surface quality. While it will be unstable if the material removal rate exceeds the threshold. In addition, the results also find that dressing conditions have a higher degree of impact than the regulation of parameters.
