| 摘 要： | 针对目前参数曲线加减速控制的不足,研究了基于NURBS曲线的插补前抛物线-直线-抛物线的S形加减速自适应控制方法,将高速加工中容易超限的弓高误差、机床所承受的加速度等参数均考虑在内,而且合理地解决了插补前加减速控制中的减速点预测困难的问题。采取优化、简化等快捷算法,实现了实时自适应的NURBS等参数曲线插补的加减速控制,并用实例进行了验证。

| Abstract: | Forehand Parabola-line-parabola S shaped Acce-Dece method based on NURBS interpolator was researched, taking chord error and jerk into consideration, solving rationally difficulty in the predetermination Dece-point. In this method, optimized and simplified algorithms are taken a step so that real-time adaptive control NURBS interpolation is realized and simulated successfully. |
