Abstract: This paper proposed a novel adaptive control method to compensate the cutting force induced tool deflection during micromilling processes. Owing to the slenderness of the micromilling cutter, the tool deflects at a certain degree depending on the magnitude of the instantaneous cutting force. The proposed intelligent adaptive control algorithm will adjust the cutting conditions online to compensate the tool deflection and therefore improving the machining accuracy. The numerical simulation results demonstrate the effectiveness of the proposed compensation strategy.

Keywords: micromilling; cutting force; tool deflection; adaptive control; micromachining; machining accuracy; numerical simulation.
