Axial self-adaptability based curve interpolation algorithm

SHEN Hong-yao,FU Jian-zhong,CHEN Zi-chen(Zhejiang Province Key Laboratory of Advanced Manufacturing Technology,Institute of Manufacturing Engineering,Zhejiang University,Hangzhou 310027,China)  
The dynamic influence on each axis will significantly influence the machining stability and product precision while high speed machining (HSM) is significant but always be ignored in most interpolators.The proposed axis-based look-ahead NURBS interpolator (ALANI) not only guarantees the contour precision of workpiece,but also confines the component acceleration according to the capability of the servo system on each axis,restricting the component jerk to avoid immoderate vibration and shocks.Based on the kinematics analysis,an algorithm of interpolation strategy modification was designed,which can efficiently modify the feedrate while encountering a bad point during the look-ahead calculation.The simulation shows that the ALANI algorithm has better characteristic compared to other interpolators.
