“…Benefit from their excellent advantages, which include fast response times, high resolution and compact size, piezoelectric actuators (PEAs) are widely used in piezoelectric-driven mechanisms, including high-precision positioning [1], [2], [3], atomic force microscopes [4], [5] and nanofabrication [6], [7]. The motion of PEAs is produced in response to an applied electric field through the converse piezoelectric effect.…”

In this paper, a novel feedforward control method is proposed to control the hysteretic nonlinearity and resonance in piezoelectric-driven mechanism. A third-order rate-dependent Rayleigh model is established according to voltage dependence and rate dependence tests using sinusoidal and triangular waveform signals. In order to verify the accuracy of this model, the tracking errors of the Rayleigh model are analyzed and a comparison of the 3D Rayleigh model and the experimental data is visualized. The modeling accuracy of Rayleigh model in minor loops is also analyzed quantitatively. The hysteresis compensation Rayleigh model is then derived based on the energy compensation method. To control the mechanical resonance in piezoelectricdriven mechanism, a triangular input signal trajectory optimization method is developed based on minimum-acceleration trajectory planning theory. The turning parts of the triangular waveform signal are replaced with smooth curves but the linear parts are retained. Experiments are conducted to demonstrate the effectiveness of the proposed control method.

“…Li et al designed and modeled a new three-dimensional ultrasonic vibration platform with tunable characteristics. Their platform can realize a variety of vibration modes including one-dimensional (linear) and two-dimensional (in-plane or out-of-plane) vibrations [ 17 ]. Schubert [ 18 ], on the other hand, superimposed ultrasonic vibration on non-conductive ceramics with high-depth-to-diameter-ratio micro-hole discharge processing, where direct vibration of the workpiece or tool can increase the micro-hole depth by increasing the feed rate and reducing the inter-polar abnormal discharge state.…”

In order to improve the surface forming quality and machining efficiency of composite materials and reduce tool wear, a two-dimensional rotary ultrasonic combined electro-machining (2DRUEM) technology with low electrical conductivity and low current density was proposed in this study. Additionally, a gap detection unit of the machining system was designed with the integration of grinding force and gap current, and the average errors and maximum errors of the model were 5.61% and 12.08%, respectively, which were better than single detection. Furthermore, the machining parameters were optimally selected via NSGA-II, and the maximum machining surface roughness error was 5.9%, the maximum material removal rate error was 5.5%, and the maximum edge accuracy error was 8.9%, as established through experiments.

“…Wang, et al studied the application of rotatory ultrasonic in machining CFRP materials under different aspects and established a material removal model. The experimental results showed that, although the cutting force decreased significantly, the surface roughness also increased under the condition of ultrasonic combination [ 12 , 13 , 14 , 15 ]. Lu, et al designed a new three-dimensional ultrasonic vibration platform with tunable characteristics, modeled it, and verified its functioning via experiments.…”

According to the machining characteristics of ceramic-particle-reinforced metal matrix composites, an experimental study on difficult-to-machine materials was carried out by two-dimensional (2D) rotatory ultrasonic combined electrolytic generating machining (RUCEGM), which organically combined an ultrasonic effect with a high-speed rotating tool electrode and electrolysis. After building the one-dimensional (1D) and 2D-RUCEGM systems, the factors influencing the combined machining process were analyzed and the experiments on RUCEGM were conducted to explore the feasibility and advantages of 2D-RUCEGM. The experimental results showed that, compared with 1D-RUCEGM, 2D-RUCEGM had higher accuracy, which increased about 21% and also reduced the machining time. Under certain conditions, the efficiency of 2D-RUCEGM was proportional to the voltage, and the machining efficiency could be enhanced by increasing the feed rate. The inter-electrode voltage detection module used in the experiment could improve the machining stability of the system.
