In the compact design of the trans-scale FTS, a voice coil motor and a dual-stage flexure mechanism are designed together with the armature of the VCM, by which a 2-DOF (degree of freedom) reciprocating motion is developed in the diamond tool for precision manufacturing. In the dual-stage flexure mechanism, stage 1 (meso-range) is driven by a VCM, while a PEA stack is used to drive stage 2 (micro-range).
Details of this project will be shared after the work is published.
The FTS consists of a Lorentz-force linear VCM and flexure mechanism. In the FTS design, the VCM is the actuating element, and the flexure mechanism is to provide support and high-precision motion guidance for the actuation. To create a compact design for the FTS system, the flexure hinge mechanism was designed in conjunction with the armature (mover) of the VCM, which developed a reciprocating motion in the diamond tool tip for diamond turning.

Voice coil actuators (VCAs) are electromagnetic devices that use the Lorentz force principle to generate actuation within relatively short stroke lengths proportional to their own length. Their name derives from their common use in loudspeakers. VCAs are particularly useful in precision motion applications, for they are free from mechanical hysteresis, force or torque ripple, and backlash due to their non-contact and continuous operation.

This thesis project was dedicated to renewable energy generation in an eco-friendly manner. In this project, a rack pinion and other unique mechanisms are implemented, which turn the moving speed beaker into a power-generating unit.
