关 键 词：NURBS Quartic Polynomial Velocity Planning Filtering CNC
摘 要：A novel algorithm based on NURBS curve is addressed for acceleration/deceleration of CNC machine tools by combining quartic polynomial velocity planning and filtering,aiming at vibration of CNC caused by sharp acceleration and *** validity has been proved *** connecting a filter after the routine results,continuous acceleration and jerk are further *** shows that this is a simple and effective algorithm to achieve further smoothing of continuous acceleration and jerk,thereby reducing machine vibration and achieving high speed,high efficiency and high precision machining.
