Demand for generating functional surface with micro texture to the large scale and complex structure has increased in industries. In order to meet such demand, it is important to develop a fast tool servo technology for milling process to generate fine pattern on freeform surface efficiently. This paper presents a newly developed machining system equipped with a fast tool servo driven by giant magnetostrictive element (GME) and its basic machining performance. The developed 3 axis machining system has aerostatic spindle equipped with the GME-driven tool servo mechanism and feed axes of a workpiece. Through actual machining experiments, the results confirmed that the developed system has capability to position a tool during milling process and can generate micro structure precisely.
