In recent years, piezoelectric actuators, represented by inertial and inchworm actuators, have been widely applied because of their high accuracy and excellent responsiveness. Despite the development of various piezoelectric actuators, there remain some flaws in this technology. The sticking point is that the piezoelectric actuators based on the friction driving principle are prone to unwanted backward motion when outputting stepping motion. It is thus urgent to explore solutions from the perspectives of principle and structure. In this paper, a clamping-drive alternating operation piezoelectric actuator is proposed, the two feet of which are driven by two piezoelectric stacks, respectively. Due to double-foot alternate drive guide movement, backward movement is prevented in theory. By adopting the double-layer stator structure, integrated processing and assembly are facilitated. Meanwhile, a double flexible hinge mechanism is installed in the stator to prevent the drive foot from being overturned due to ineffectiveness and premature wear. In addition, the stator is equipped with the corresponding preload mechanism and clamping device. After the cycle action mechanism of one cycle and four steps is expounded, a model is established in this study to further demonstrate the principle. With the prototype produced, a series of experiments are performed. In addition, the amplitude of actuation of the stator is tested through amplitude experiment. The performance of the stator is evaluated by conducting experiments in the alternating step and single step actuation modes. Finally, the test results are analyzed to conclude that the actuator operating in either of these two modes can meet the practical needs of macro and micro actuation.

Three-dimensional elliptical vibration assisted cutting (3D-EVC) technology has been widely used in many high-precision technical fields due to its high-efficiency processing characteristics. However, the hysteresis and nonlinearity caused by the piezoelectric drive in the 3D-EVC system will impact the system control accuracy. This paper mainly studies the hysteresis and nonlinearity of the system, the feedforward-gray predicted fuzzy PID compound controller based on the generalized Bouc-Wen hysteresis nonlinear model and it is designed to realize the hysteresis compensation of the system. In this paper, input voltage and output displacement are represented by a mathematical relationship, and this relationship of the 3D-EVC system will be described by the generalized Bouc-Wen model. The improved flower pollination algorithm (IFPASO) is adopted in the identification process of parameters. A compound control strategy is formed based on traditional feed-forward control combined with fuzzy PID feedback control to compensate for hysteresis and nonlinearity, and an improved gray prediction model is introduced into the feedback loop. The 3D-EVC system tracking experiment verifies the effectiveness of the designed compound controller. Experiments have proved that the hysteresis component of the system is significantly reduced after the use of the compound controller for hysteresis compensation, and the system has a higher degree of stability.

“…The traditional machining methods are sometimes difficult to satisfy the needs of today's advanced materials. The ultrasonic vibration-assisted turning technology is a machining method that combines traditional turning and ultrasonic vibration, which can reduce cutting force [2][3][4], decrease cutting heat [5][6][7], and improve surface quality [8][9][10] of the workpiece.

In this paper, the peak heights of several turning methods were analyzed theoretically. Based on the results of theoretical analysis, a 3D-UVAT device driven by a single actuator was developed. To validate this design, the theory and experiment of 3D-UVAT have been undertaken. The FEA results show that design is safe, and can achieve obvious displacements in X-axis, Y-axis, and Z-axis. In the experiment, 304 stainless steel was chosen as experimental material. For comparison, CT, UVAT, and UEVT experiments were also carried out. The experimental results show that with the help of ultrasonic vibration, the surface grooves and defects are significantly reduced. This phenomenon is more obvious on machined surface obtained by 3D-UVAT. Three-dimensional surface topography shows that the roughness value Sa obtained by 3D-UVAT is smaller than CT and UVAT. Under some cutting conditions, the roughness value Sa of machined surface obtained by 3D-UVAT is smaller than UEVT. Thus, the results of theory and experiment proved that the 3D ultrasonic vibration-assisted turning driven by a single actuator has a great potential in improving the quality of machined surface.
