Micromachining tools need to cut harder materials and needs high accuracy. At this trend, machining tools need more powerful motors and accurate control methods. So, the exact estimation of the motion of machine tool is needed.Also the needs of miniature component markets are increased according to the growth of IT and BT industry. While the components are various, the number is small at this trend. To react quickly to rapidly changing situations, reconfigurable multi-axis machine systems are needed to machine these parts[1-7].
