The positioning resolution and repeatability of the end platform is nanometer scale for the adoption of high precision actuator piezoelectric ceramics.
The development of the intelligent fixturing will be focused mainly in the conception of a high precision actuator capable of moving the large part with the required tolerance.
This study suggests that the NN-xBT system and related NN-based materials can be considered as potential materials used in high-precision actuators, and also evoke the interest to study the origin of such ultra-low hysteresis electric field-induced strains in the fundamental research aspect.
Since a traditional mechanical transmission structure cannot achieve high precision, a piezoelectric actuator is usually applied to drive the mechanism because of its high resolution, high accuracy, and large driving force.
Generally, linear motor is used as actuators for high precision stage which requires long stroke, high speed and high precision capability.
In this paper, a spatial hybrid motion mechanism with 3-DOFs is developed that integrates two types of motion through only one compliant mechanism: a macro motion driven by DC servomotors for large workspace and a micro motion driven by PZT actuators for high precision.
The cardiovascular system simulator consists of high-bandwidth actuators allowing a high precision hardware-in-the-loop hydrodynamic interface in connection with physiological circulatory models calculated in real-time.
This paper presents a high precision positioning mechanism design with dual actuator.
In order to satisfy the requirements of next generation systems such as high resolution, high speed, and long stroke, the use of a linear motor with a MST array as an actuator in a high precision positioning system is recommended from the results obtained here.
In this paper, we have achieved the large stroke actuating and the high precision positioning, as well as realized a multi-degree-of-freedom in-plane motion using the developed Galfenol impact drive mechanism (IDM) actuator.
