加工路径段进给速度的转接及加减速处理方法(Transiting and Acceleration/Deceleration Methods for Feed-speed of Machined Path Segments)
高速加工 进给速度 加减速
2010/1/28
针对高速高精加工对数控系统在进给速度控制方面的要求,根据相邻路径段间的转接角大小建立了可直接进行段间转接的条件,并研究了该条件不成立时对转接速度的修正问题。提出了段内加减速的处理基本原则,并在保持路径段长度不变的基础上对路径段内的进给速度重新进行规划,避免了以往插补前加减速方法中减速点和终点预测困难的问题。实际计算结果表明,相对零速度转接加减速处理方法,所提出的方法在同样保证加工精度等基础上提高了...
