磨削(Grinding Process)，是金屬切削加工中，常用的精加工方法之一，因此一般元件表面的精加工製程是利用磨削來獲得所需元件的表面品質，然而工件表面品質的優劣皆必須等待磨削加工後經由量測而得知，為能夠在加工時判斷磨後工件表面品質之趨勢及可能的優劣，實有必要在加工線上即時來判斷表面品質的能力。

本研究將提出一磨削能量之觀點，藉移除單位體積所需之能量(比磨削能)及砂輪旋轉線速與工件進給速度之速度比等二者作為線上觀察工件表面品質的關鍵因子，並透過適當規劃的磨削加工實驗，來探討比磨削能及速度比對工件表面品質的關聯。

由磨削實驗數據之分析整理，得知比磨削能及速度比與工件表面品質之表面粗糙度、表面殘留應力以及表面微硬度均呈現一指數的關係，並發現較大的比磨削能及速度比將可獲得較佳的工件表面粗糙度，但卻會造成較大的磨後工件表面殘留應力，同時也將會降低工件表面的微硬度；本研究並根據比磨削能對工件表面品質之關聯，整合磨削相關的理論建立一磨削預測模型，以利磨後工件表面品質之預測。

Grinding process in one of the common method for precision machining of metals, which is typically applied to the demanded. However, the surface quality of grinding component can’t be realized until it is measured. In order to confirm the tendency and the possible surface characteristic of the grind component, it would seems necessary to monitor the grinding process to instantaneously realize the surface quality.
A grinding energy hypothesis for surface quality monitory was proposed in this research. For on-line observation of workpiece quality, two quality were used for the purpose the amount of grinding energy consumed per unit volume ( specific grinding energy ), as well as the speed ratio of wheel surface speed to workpiece feed ratio. A grinding experiment was conducted to conform the relationship theory two quantity and grinding surface quality.
The experiment result was analyzed to found out that the grinding surface quality was exponentially proportional to both specific grinding energy and the speed ratio. It was also realized that the higher the specific energy and the speed ratio, a better grind surface well be generated which a larger surface residual stress could be reduced of thus lowering the surface micro-hardness corresponding. A predictive grinding model was also developed in this research work, for the purpose of grinding surface quality prediction.
