New aircraft are design with one piece flow of monolithic component which contains of thin wall flange and rib. The poor stiffness of the thin wall structure tends to deflect the part during the machining process which resulting in dimensional surface errors. Cutter geometry has a direct influence on the cutting performance and should not be neglected in the machining consideration. Driven by the need to constantly increases the machining efficiency and part accuracy, this paper aim to develop a new cutter design specifically to control the part deflection by optimizing the cutter geometrical features namely helix angle and pitch angle.
