进给速度一直是数控机床最重要的指标之一。而线段之间的转角速度则严重影响着进给速度,本文就将在分析单线段以及两线段相连的情况下各种运动轨迹来得出最佳转角速度的数学模型,并给出适合于数控系统开发的方法,而且已经在HL-B0408数控机床的设计上加以实现。实例表明给出的算法能明显的提高数控机床的进给速度,从而提高效率。
Feedrate is one of the most important indexes in the CNC system, and the transition velocity of the linking lines or arcs influence the feedrate heavily The paper give a best-transitionvelocity model based on the analysic of the suitiation single and linking lines,and give the way to design in CNC system, which is all ready accomplished in HL-B0408 CNC systemThe example demonstrates the CNC system adopting the algorithm improves the feedrate.
