Study on a Fast Tool Servo (FTS) Driven by Piezoelectric Ceramic

Abstract

It is designed a Fast Tool Servo (FTS) device which based on piezoelectric ceramic and jointed by flexible hinge. The flexible hinge has been analyzed and optimized both by the theoretical calculation and finite element analysis; and it has been physically manufactured and tested by means of pressure sensor and laser interferometer. The stiffness model was established. The driving voltage and displacement relationship has been revealed. The results indicate that this FTS system can reach a travel range for 60μm,the frequency response precedes 150Hz within 39μm travel range.

Compensation machining of freeform based on fast tool servo system

“…In the 1980s, Lawrence National Laboratory of micro feed technology first developed micro piezoelectric knife drive system in the United States. After more than 30 years of development, a series of high-performance micro nano feed systems for FTS and a set of mature manufacturing theory and processing technology system have been developed [9][10][11][12][13]. With the influence of fatigue reliability, Liu J F et al developed a high-frequency response and large stroke fast knife servo device, and machined a submicron precision microstructure array on the cylindrical surface [14,15].…”

3D printing of optical components via free-radical frontal polymerization

“…There are several different variations of FTS, where the classification of each is based on the driving mechanism behind the oscillatory tool. The three most common variations are piezoelectric (PZT) [50,56,90], Lorentz force (LRT) [62,95,108], and Maxwell normal stress motor-driven (MNM) [69,70,105].…”
