A study on the improvement of surface waviness by cutting force control

밀링 머신의 절삭력 제어를 통한 표면 굴곡도 향상에 관한 연구

To improve the surface waviness in the peripheral milling, since the tool deflection is largely affected by cutting force, the feedrate is controlled so that the cutting force measured in the normal direction to the workpiece is constant. A discrete time first order model between the feedrate and the tool deflection is derived for the control. The experimental results show that the surface waviness is greatly improved by the proposed method.
