| Outline of Final Research Achievements |
Demand for generating functional micro patterns on a curved surface such as molds has increased in various industrial sectors. In order to meet the demand, a new advanced micro machining system which generates curved form and fine patterns simultaneously and efficiently was developed. The machining system has a fast tool servo mechanism for milling process driven by a giant magnetostrictive actuator. The results of actual machining experiments confirmed that the developed system has capability to position the end mill precisely during machining and to generate patterned curved surface. Furthermore, a new monitoring method based on photoelectric effect was proposed to detect approach of a cutting tool, and its effectiveness was confirmed through the basic experiment.
