A dynamic model of drilling is used to study the effects of process damping on tool stability and hole form. The formulation leads to an eigenvalue problem yielding cutting speed and depth of cut combinations that produce borderline stable solutions to the equations of motion. The addition of process damping is seen to lead to the instability of low-frequency modes that resemble those found in practice.
