Chatter vibration in deep drilling is investigated. A model is prepared to define the stability lobs according to feed rate and spindle speed. Then a detailed discussion for finding ways of performing faster operation is done. Effects of tool length on chatter stability lobs are determined, and then different process optimization methods due to this parameters are investigated. It was shown that step drilling with different tool lengths is a good way to avoid regenerative chatter and do the operation faster.
