“…The ball screw is a transmission device that converts linear motion into rotary motion or rotary motion into linear motion, and it has the advantages of high position accuracy, load capacity and fatigue life [1][2][3]. The dynamic characteristic of the feed system is the key factor to determine the machining accuracy of the workpiece and stability of the cutting process [4,5], and the nonlinear contact relationship between balls and raceways leads to the complexity and instability of the worktable vibration [6,7].…”

In this paper, a nine degree-of-freedom dynamic model of the ball screw feed system considering the contact nonlinearity between balls and raceways is established to analyze the vibration characteristics. The position relationship between raceway centers for the ball screw and bearings is determined by using the homogeneous coordinate transformation, and then the restoring force functions along the axial and lateral directions are derived. The dynamic equations of the feed system are solved by using Newmark method, and the proposed model is verified by the experimental method. Furthermore, the effect of the excitation amplitude on the axial vibration of the feed system is investigated by the frequency-amplitude curve and 3-D frequency spectrum. With the increase of excitation amplitude, the dynamic response of the feed system exits the softening, hardening type nonlinearity and jump phenomenon. Additionally, the effects of the initial contact angle, length of screw shaft and number of loaded balls on the axial vibration of the feed system in the resonance region are discussed. The results show that the dynamic model established in this paper is suitable for improving the machining accuracy and stability of the ball screw feed system.

The deflectometry provides an optical testing method with ultra-high dynamic range. In this paper, a microscopic testing method based on deflectometric technique is proposed to quantitatively evaluate the microstructures according to the wavefront aberration. To achieve the real-time and accurate wavefront testing for microstructure evaluation, a colorcoded phase-shifting fringe pattern is applied to illuminate the test object. It avoids the sequential projection of multistep phase-shifting fringes in traditional deflectometry, enabling the transient wavefront testing. The feasibility of the proposed transient microscopic testing method is demonstrated by the experiment. The proposed method enables accurate and transient testing of microstructures with high dynamic range, minimizing the environmental disturbance.

“…Although several means of precision positioning exist, many are either unsuitable or do not readily lend themselves to ultra-precision applications. A common method of positioning is the combination of ball screw with electric motor (Caracciolo and Richiedei, 2014; Fukada et al, 2011; Henke et al, 2015; Tarkowski et al, 2016; Tenzer and Mrad, 2004). While having the capacities of high stiffness, long range, large thrust, and wide speed range, ball screws suffer from lost motion and wind up (Henke et al, 2015; Tenzer and Mrad, 2004).…”

This article presents the piezoelectric ultrasonic linear actuator based on binate feet driving. The actuator is equipped with a rhombus binate feet mechanism to generate two synchronous rectangle driving trajectories. With the help of the two synchronous trajectories, the proposed actuator can deliver stable long-range motion (the designed maximum stroke is 19 mm) accompanying with large loading capacity and high driving resolution. The configuration and operational principle are described in detail and the driving trajectory of the binate feet is analyzed. Finite element analysis is conducted to investigate the static deformation and stress status of the driving mechanism at every step. The experimental system is established to test the performance of the actuator prototype and the results indicate that the prototype can be operated stably step by step and all steps have high reproducibility. The driving resolution (minimum step length) of the actuator prototype is 25.9 nm. The maximum loading capacity and the maximum thrust are 37.2 and 3.2 N, respectively. The experimental results also confirm that the designed actuator can achieve various motion velocities by changing the driving voltage and driving frequency.
