Abstract:The piezoelectric stick-slip stage is very important in industrial manufacturing and precision machining. However, due to the stick-slip principle, it is inevitable to produce backward motion, which leads to a decrease in precision and efficiency. A novel smooth-drive scheme for piezoelectric stage is proposed by coupling stick-slip motion and inertial impact in this paper. In the coupling counteract phase, the sliding friction force of stick-slip driving mechanism (SDM) is counteract by the impact force of in… Show more
