Abstract: As a new kind of NC saw machine, milling flying saw has a great market prospect in pipe processing lines. The principle of suppressing vibration by milling with varying milling parameters was introduced to guide a better design of the control system of the milling flying saw. By applying different processing parameters, such as feed rate and spindle speed, the forced vibration and chatter were suppressed effectively during the processing. The processing quality and efficiency were also improved.
Key words: milling flying saw; chatter; forced vibration; servo
