| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程研究所 === 84 === In this paper, an active control system is posped to suppress
vibration in turing operations. In the developed control
system, the vibration signal of the cutting system is phase
shifted, amplified, and then fed into a piezoelectric actuator
to generate a piezoelectric force. The piezoelectric force is
fed back to the cutting system to suppress the chatter
vibration on system. It is shown that the piezoeletric force
can be treated as the stiffness force or damping force relative
to the for on the system, depending on the phase shifting of
the vibration signal. Finally, an expermental model is
established and verified to illustrate the posped control
strategies.
