摘要：
In this study, piezoelectric actuator, flexure guide, power transmission element and control method are considered for nano-positioning system apparatus. The main objectives of this thesis were to develop 2-axis nano-stage which enables 2-axis control with the aid of piezoelectric actuator, and to improve the precision of the ultra- precision lathe (UP2) which is responsible for the ductile mode machining of the hardened-brittle material where the machining uses a the single-crystal diamond. Through simulation and experiments on ultra-precision positioning, stability and priority ogf the nano-positioning system with 2-axis nano-stage and control algorithm are developed using Matlab/Simulink. Then the system, is applied to analyze surface morphology of the titanium alloy (Ti-6Al-4V)
