This paper presents collaboration model for information system of engineering collaboration Hub system for mold industry, the e-Manufacturing Hub System. It is shown how the collaboration ,between companies in the field of the mold industry, can progressed by collaboration templates of engineering collaboration Hub system. The e-Manufacturing Hub System, is planned and driven by Korean Government and KITECH, has a goal to establish online engineering collaborative value chain in a consortium of small and medium mold related companies. We have researched the collaboration model of this consortium for the use of the e-Manufacturing Hub System. In this paper, some templates for managing internal engineering data and job structure in the viewpoint of individual company and some templates for sharing engineering data and co-work between each other companies.

In this study, ultrasonic vibration tool designed and made by using FEM analysis. And machining test was carried out in various machining conditions using ultrasonic vibration capable CNC machine. For work material, alumina ceramic (Al₂O₃) was used while for tool material diamond electroplated grinding wheel was used. To evaluate ultrasonic vibration effect, grinding test was performed with and without ultrasonic vibration in same machining condition. In ultrasonic mode, ultrasonic vibration of 20㎑ was generated by HSK 63 ultrasonic actuator. The two grinding speeds, 1.67㎧ and 3.35㎧, were applied. On the other hand, grinding forces were measured by KISTLER dynamometer.
