摘　　要：针对五轴数控机床加工过程中难以对减速点精确预测以及旋转轴速度均分所产生的运动不协调等问题,提出了一种新的梯形加减速规划方法,减少了数控机床的加工时间,显著提高了机床的工作效率,从而验证了该五轴线性插补中进给速度的控制方法是合理有效的。In order to solve the problems that it is difficult to accurately predict the deceleration point and the motion disharmony caused by the equal velocity division of the rotating axis in the machining process of the five-axis NC machine tool,a new trapezoidal acceleration and deceleration planning method is proposed,which reduces the machining time of the NC machine tool and significantly improves the working efficiency of the machine tool,and thus the control method of the feed speed in the five-axis linear interpolation is verified to be reasonable and effective.
