This paper deals with the micro turning property of setting angle using diamond tool. The bed of the system has used the granite which has the thermal and vibrational characteristics superior to the cast iron bed for the common machine tool. To minimize the inner and outer vibration of the turning system, an air pad system was manufactured and tested. The aero-static spindle system which has the excellent rotation accuracy was designed and manufactured. As a result of the micro-cutting test on aluminum alloy, tool setting angel have effected on surface roughness. From the result, the micro-cutting conditions hope to provide the useful actual data using in industrial fields.

The high speed precision spindle, which is an important element part of industrial machinery such as micro drilling, high speed machine tools and the atomizer. In this study, the aero-static spindle was designed and a stiffness analysis of air bearing was carried out to investigate the optimal design parameter for the high speed spindle.

This paper deals with the ultrasonic vibration cutting for the precision machining of aluminum alloy. When the ultrasonic vibration is applied on the tool, the cutting tool makes periodical contact with workpiece. And, the cutting is performed by vibrating impact force while the cutting tool contacts the workpiece. In this paper, the horn of ultrasonic vibration system were designed and manufactured, to compare the ultrasonic vibration cutting with the conventional cutting, the machined surface roughness of aluminum alloy in turning were experimentally measured. The experiments revealed that the ultrasonic vibration cutting had the best surface roughness than the conventional cutting under the same cutting condition.
