Abstract—In recent years, electronic devices have become
lighter, thinner, shorter, smaller, and more multifunctional,
motivating micro drilling technology to become more
sophisticated. To meet the demands of electronic applications,
this paper proposes a drilling machine tool with a
counterbalance vibration control mechanism. In this report,
focusing on the timing of table feed rate changes during drilling,
drilling experiments were conducted using four drilling paths
while changing the table movement direction and feed rate
along the machining path. The accuracy of the positions of the
drilled holes and condition of the drill edge after drilling were
then evaluated.
Index Terms—Vibration, counter balance, machine tool,
