碩士 === 國立高雄第一科技大學 === 機械與自動化工程所 === 90 === 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.
