摘　　要：步进电动机加减速控制是数控火焰切割机的关键技术之一。五阶段S曲线加减速算法的理论分析表明,该算法的速度与时间关系一阶连续,加速度曲线为连续曲线,可以避免数控系统的加减速冲击。该算法在数控火焰切割机中的应用表明,五阶段S曲线加减速算法是一种适合于高速运动的柔性加减速算法,具有运动精度高、易于实现的特点。The acceleration and deceleration control of stepping motors is one of the most key technologies of the CNC flame cutting machine.The theoretical analysis of five-stage S curve acceleration and deceleration algorithm shows that there is a one-order continuous relationship between time and speed,and the acceleration curve of the algorithm is a continuous curve,which is helpful to avoid the impact when the CNC system accelerates and deceler-ates.Its application to CNC flame cutting machines shows that the algorithm is flexible and suitable for high speed movement.The algorithm is characterized by high movement precision and easiness of implementation.
